           getline.c
             tputs_fp is now only declared if using termcap or
             terminfo.
           getline.c libtecla.map man3/gl_get_line.3
           man3/gl_terminal_size.3
             I added a public gl_terminal_size() function for
             updating and querying the current size of the terminal.
           update_version configure.in libtecla.h
             A user noted that on systems where the configure script
             couldn't be used, it was inconvenient to have the version
             number macros set by the configure script, so they are
             now specified in libtecla.h. To reduce the likelihood
             that the various files where the version number now
             appears might get out of sync, I have written the
             update_version script, which changes the version number
             in all of these files to a given value.

           getline.c history.c history.h man3/gl_get_line.3
             I added a max_lines argument to gl_save_history(), to
             allow people to optionally place a ceiling on the number
             of history lines saved. Specifying this as -1 sets the
             ceiling to infinity.

           configure.in configure
             Under digital unix, getline wouldn't compile with
             _POSIX_C_SOURCE set, due to type definitions needed by
             select being excluded by this flag. Defining the
             _OSF_SOURCE macro as well on this system, resolved this.

           getline.c libtecla.h history.c history.h man3/gl_get_line.3
           man3/gl_group_history.3
             I implemented history streams. History streams
             effectively allow multiple history lists to be stored in
             a single history buffer. Lines in the buffer are tagged
             with the current stream identification number, and
             lookups only consider lines that are marked with the
             current stream identifier.
           getline.c libtecla.h history.c history.h man3/gl_get_line.3
           man3/gl_show_history.3
             The new gl_show_history function displays the current
             history to a given stdio output stream.

           getline.c
             Previously new_GetLine() installed a persistent signal
             handler to be sure to catch the SIGWINCH (terminal size
             change) signal between calls to gl_get_line(). This had
             the drawback that if multiple GetLine objects were
             created, only the first GetLine object used after the
             signal was received, would see the signal and adapt to
             the new terminal size. Instead of this, a signal handler
             for sigwinch is only installed while gl_get_line() is
             running, and just after installing this handler,
             gl_get_line() checks for terminal size changes that
             might have occurred while the signal handler wasn't
             installed.
           getline.c
             Dynamically allocated copies of capability strings looked
             up in the terminfo or termcap databases are now made, so
             that calls to setupterm() etc for one GetLine object
             don't get trashed when another GetLine object calls
             setupterm() etc. It is now safe to allocate and use
             multiple GetLine objects, albeit only within a single
             thread.

           version.c Makefile.rules
             I added a function for querying the version number of
             the library.

26/09/2001 [e-mail]

           getline.c man3/gl_get_line.3
             I added the new gl_watch_fd() function, which allows
             applications to register callback functions to be invoked
             when activity is seen on arbitrary file descriptors while
             gl_get_line() is awaiting keyboard input from the user.

           keytab.c
             If a request is received to delete a non-existent
             binding, which happens to be an ambiguous prefix of other
             bindings no complaint is now generated about it being
             ambiguous.

           getline.c history.c history.h man3/gl_get_line.3
           libtecla.map demo.c
             I added new public functions for saving and restoring the
             contents of the history list. The demo program now uses
             these functions to load and save history in ~/.demo_history.

23/09/2001 [e-mail]

           getline.c
             On trying the demo for the first time on a KDE konsole
             terminal, I discovered that the default M-O binding
             to repeat history was hiding the arrow keys, which are
             M-OA etc. I have removed this binding. The M-o (ie the
             lower case version of this), is still bound.

18/09/2001 [e-mail]

           getline.c man3/gl_get_line.3 libtecla.map
             Automatic reading of ~/.teclarc is now postponed until
             the first call to gl_get_line(), to give the application
             the chance to specify alternative configuration sources
             with the new function gl_configure_getline(). The latter
             function allows configuration to be done with a string, a
             specified application-specific file, and/or a specified
             user-specific file. I also added a read-init-files action
             function, for re-reading the configuration files, if any.
             This is by default bound to ^X^R. This is all documented
             in gl_get_line.3.

08/09/2001 [e-mail]

           getline.c man3/gl_get_line.3
             It is now possible to bind actions to key-sequences
             that start with printable characters. Previously
             keysequences were required to start with meta or control
             characters. This is documented in gl_get_line.3.

           getline.c man3/gl_get_line.3
             A customized completion function can now arrange for
             gl_get_line() to return the current input line whenever a
             successful completion has been made. This is signalled by
             setting the last character of the optional continuation
             suffix to a newline character. This is documented in
             gl_get_line.3.

05/07/2001 Bug reported by Mike MacFaden, fixed by mcs

           configure.in
             There was a bug in the configure script that only
             revealed itself on systems without termcap but not
             terminfo (eg. NetBSD). I traced the bug back to a lack of
             sufficient quoting of multi-line m4 macro arguments in
             configure.in, and have now fixed this and recreated the
             configure script.

05/07/2001 Bug reported and patched by Mike MacFaden (patch modified
           by mcs to match original intentions).

           getline.c
             getline.c wouldn't compile when termcap was selected as
             the terminal information database. setupterm() was being
             passed a non-existent variable, in place of the term[]
             argument of gl_control_strings(). Also if
             gl_change_terminal() is called with term==NULL, "ansi"
             is now substituted.

02/07/2001 Version 1.3.3 released.

           getline.c expand.c cplmatch.c
             Added checks to fprintf() statements that write to the
             terminal.
           getline.c
             Move the cursor to the end of the line before suspending,
             so that the cursor doesn't get left in the middle of the
             input line.
           Makefile.in
             On systems that don't support shared libraries, the
             distclean target of make deleted libtecla.h. This has
             now been fixed.
           getline.c
             gl_change_terminal() was being called by gl_change_editor(),
             with the unwanted side effect that raw terminal modes were
             stored as those to be restored later, if called by an
             action function. gl_change_terminal() was being called in
             this case to re-establish terminal-specific key bindings,
             so I have just split this part of the function out into
             a separate function for both gl_change_editor() and
             gl_change_terminal() to call.

           getline.c
             Signal handling has been improved. Many more signals are
             now trapped, and instead of using a simple flag set by a
             signal handler, race conditions are avoided by blocking
             signals during most of the gl_get_line() code, and
             unblocking them via calls to sigsetjmp(), just before
             attempting to read each new character from the user.
             The matching use of siglongjmp() in the signal
             handlers ensures that signals are reblocked correctly
             before they are handled. In most cases, signals cause
             gl_get_line() to restore the terminal modes and signal
             handlers of the calling application, then resend the
             signal to the application. In the case of SIGINT, SIGHUP,
             SIGPIPE, and SIGQUIT, if the process still exists after
             the signals are resent, gl_get_line() immediately returns
             with appropriate values assigned to errno. If SIGTSTP,
             SIGTTIN or SIGTTOU signals are received, the process is
             suspended. If any other signal is received, and the
             process continues to exist after the signal is resent to
             the calling application, line input is resumed after the
             terminal is put back into raw mode, the gl_get_line()
             signal handling is restored, and the input line redrawn.
           man/gl_get_line(3)
             I added a SIGNAL HANDLING section to the gl_get_line()
             man page, describing the new signal handling features.

21/05/2001 Version 1.3.2 released.

           getline.c
             When vi-replace-char was used to replace the character at
             the end of the line, it left the cursor one character to
             its right instead of on top of it. Now rememdied.
           getline.c
             When undoing, to properly emulate vi, the cursor is now
             left at the leftmost of the saved and current cursor
             positions.
           getline.c man3/gl_get_line.3
             Implemented find-parenthesis (%), delete-to-paren (M-d%),
             vi-change-to-paren (M-c%), copy-to-paren (M-y%).
           cplfile.c pcache.c
             In three places I was comparing the last argument of
             strncmp() to zero instead of the return value of
             strncmp().

20/05/2001 [e-mail]

           getline.c man3/gl_get_line.3
             Implemented and documented the vi-repeat-change action,
             bound to the period key. This repeats the last action
             that modified the input line.

19/05/2001 [e-mail]

           man3/gl_get_line.3
             I documented the new action functions and bindings
             provided by Tim Eliseo, plus the ring-bell action and
             the new "nobeep" configuration option.
           getline.c
             I modified gl_change_editor() to remove and reinstate the
             terminal settings as well as the default bindings, since
             these have editor-specific differences. I also modified
             it to not abort if a key-sequence can't be bound for some
             reason. This allows the new vi-mode and emacs-mode
             bindings to be used safely.
           getline.c
             When the line was re-displayed on receipt of a SIGWINCH
             signal, the result wasn't visible until the next
             character was typed, since a call to fflush() was needed.
             gl_redisplay_line() now calls gl_flush_output() to remedy
             this.
