Revised editline library

Revised editline library

[rsalz]

I've spent some time working on the editline library.
Thanks to Simmy for his help and permission.  The README
is attached.  Source is on ftp.uu.net, ~ftp/tmp/editline.shar.Z;
email me if you can't FTP.  Once I get feedback I'll post it to the
net.

To use it, enable the READLINE #define in rc (not EDITLINE).
	/r$
This is a line-editing library.  It can be linked into almost any
program to provide command-line editing and history recall.

It is call-compatible with the FSF readline library, but it is a
fraction of the size (and offers fewer features).  It does not use
standard I/O.

Configuration is done in the Makefile.  Type "make testit" to get
a small slow shell for testing.

An earlier version was distribution with Byron's rc.  Principal
changes over that version include:
	Faster.
	About 10% smaller.
	Written in K&R C, but ANSI compliant (gcc all warnings)
	Propagates EOF properly; rc trip test now passes
	Doesn't need or use or provide memmove.
	More robust
	Calling sequence changed to be compatible with readline.
	Test program, new manpage, better configuration

Enjoy,
	Rich $alz
