          This efun is only available if __OLD_ED__ is defined.

          This is a funny function. It will start a local editor on an
          optional file.  This editor is almost UNIX ed compatible.
          When in the editor type 'h' for help.

          The <write_fn> function allows the mudlib to handle file
          locks and administrative logging of files modified.  When
          the editor writes to a file, the driver will callback the
          <write_fn> function twice.  The first time, the function is
          called before the write takes place -- <flag> will be 0.  If
          the function returns TRUE, the write will continue,
          otherwise it will abort.  The second time, the function is
          called after the write has completed -- <flag> will be non-
          zero.  This callback function should have the form:

               int write_fn(string fname, int flag)

          When the editor is exited, the driver will callback the
          <exit_fn> function.  This function allows the mudlib to
          clean up.  This callback function has the form:

               void exit_fn()

          The optional <restricted> flag limits the editor's
          capabilities, such as inserting a file, and saving using an
          alternate file name.
