>Description:

The termcap entry for xterm is false, it says that erase key sends ^H,
while most systems send ^?.

If kb definition is removed, tset -I seems to default to ^H, not
CERASE.  The behaviour seems weird:

(clean environment, tcsh, no .cshrc or .login)

> tset -I
Erase set to backspace.

stty shows ^H

> setenv TERM xterm (one that has been fixed to kb=^?)
> tset -I
Erase is backspace.

stty still shows ^H

> setenv TERMCAP /etc/termcap
> tset -I
Erase set to backspace.

This is fancy; it needs TERMCAP defined, though it is still reporting
that it is setting erase to backspace, while it should be saying
delete.  The code looks odd; like it was missing something?

>How-To-Repeat:

termcap problem:
	rlogin freebsd2-machine
	tset -I
	sh
	stty everything (shows erase key as ^H)
	
tset problem:
	remove kb=^H
	tset -I
	stty everything (shows erase key as ^H)

>Fix:
	
	tset -I for terminal which doesn't have kb definition probably
should default to CERASE so that it would be consistent with other
systems.

	xterm termcap entry probably should contain kb=^?
