/*
 * The following defines control the inclusion of "optional" features. As
 * the code size of the editor grows, it will probably be useful to be able
 * to tailor the editor to get the features you most want in environments
 * with code size limits.
 *
 * TILDEOP
 *	Normally the '~' command works on a single character. This define
 *	turns on code that allows it to work like an operator. This is
 *	then enabled at runtime with the "tildeop" parameter.
 *
 * HELP
 *	If defined, a series of help screens may be views with the ":help"
 *	command. This eats a fair amount of data space.
 *
 * TERMCAP
 *	Where termcap support is provided, it is generally optional. If
 *	not enabled, you generally get hard-coded escape sequences for
 *	some "reasonable" terminal. In Minix, this means the console. For
 *	UNIX, this means an ANSI standard terminal. See the file "term.h"
 *	for details about specific environments.
