Changes to elvis for 386 COHERENT, from version 1.5 to date.
Fri Jul  3 19:17:43 1992 CDT

1.  Beep doesn't work if /etc/termcap for the terminal lacks a "vb" entry.
Change is in tio.c/beep():
--
	else if (*o_errorbells)
	{
#if COHERENT
		tputs("\007", 1, faddch);
#else
		ttywrite("\007", 1);
#endif
	}
This fix appeared in the 1.6 release of elvis.
--

2.  If /etc/termcap for your terminal has kl=^H, then you can't backspace
properly in input mode.  Change is in curses.c/starttcap():
--
	mayhave(&KL, "kl");		/* left */
#if COHERENT
	if (strcmp(KL, "\b")==0)
		KL = 0;
#endif
	mayhave(&KR, "kr");		/* right */
Something like this appeared in 1.6, but used KR instead of KL.  I changed
it again.
-- 

3.  I may log in from the system console (which supports color changes)
or from a monochrome terminal.  My .exrc has a color setting.  To avoid
a cascade of "set color..." messages when logging in at the terminal,
I changed curses.c/ansicolor():
--
	/* if not ANSI-ish, then fail */
	if (strcmp(UP, "\033[A") && strcmp(UP, "\033OA"))
	{
#if COHERENT
		return 1;
#else
		msg("Don't know how to set colors for this terminal");
		return 0;
#endif
	}
Changed again in 1.6.
--

4.  In a similar vein to #3, if my terminal doesn't have function keys
but the console does, I don't want to flip through a batch of error
messages when logging in on the console, so I changed cmd1.c/cmd_map():
--
			if (FKEY[key])
				mapkey(FKEY[key], mapto, bang ? WHEN_VIINP|WHEN_VIREP : WHEN_VICMD, fnames[key]);
#if !COHERENT
			else
				msg("This terminal has no %s key", fnames[key]);
#endif
Changed again in 1.6 - hws.

Added in 1.6:

5.  config.h - TMPDIR -> /usr/tmp like minix

6.  vi.h no longer needs special case for COHERENT on fcntl.h

7.  Added printf to ref to display name of file where the symbol is defined.

8.  Changed parser in ctags.c - with "-v" on, it was recognizing
    ^int	foo();$
    as a variable declaration.

9.  Regarding the shift-K command in elvis - if you set "kp" as in
    coherent.rc, you will get COHERENT on-line help for such things
    as printf.  Or you can set it to just help (for COHERENT command
    help), or man (for the lengthier COHERENT manual entries), or to
    ref for the elvis default.  In this case, it is helpful to set
    TAGPATH if your sources are spread over several directories.

10. Added coherent.rc file with colors for VGA coherent console, kp
    setting so shift-K gives you COHERENT library help on the word
    under the cursor.

11. To allow work with preliminary X11, add code in curses.c to check
    the environment for COLUMNS and LINES.

12. Now that VMIN/VTIME are working, use the version of ttyread() in
    unix.c that uses these.  This improves response time to ESC markedly!

13. config.h - COH 386 cc now sends error output to stderr, so avoid
    special REDIRECT.
