Description Kevin Street 1999-10-31 00:30:00 UTC 
	Emacs run on the console is unusable because it scrambles the
	screen.  Problem caused by the late August (?) changes to -current
	which replaced libtermcap with a symlink to libncurses.

	Emacs tries to decode the string returned from tgetstr itself.
	Since the change in current the string is now in terminfo format
	rather than termcap format.
 
	The following patch forces Emacs to use the library
	versions of tparm and tgoto to do the decoding rather than 
	rolling its own.  It works by using the module intended for 
	Emacs running on terminfo machines (ie. it uses terminfo.c 
	rather than tparam.c).  I tried this (briefly) on -current 
	and -stable and it seems to work ok. 

	See also pr bin/14202 from Peter S. Housel.

Fix: Install the following as ports/editors/emacs20/patches/patch-ce
	or merge this patch with patch-ca since they both affect
	src/Makefile.in	

	Note: similar patches are likely needed for the other emacs ports.
How-To-Repeat: 
	Build the emacs port on current after the libtermcap changes.
	Run emacs on a text console.  Move the cursor.

Proposed patch has been tested by several people (including yours truly) and 
found to work as advertised. Over to maintainer.
