Beg your pardon, but...
(1) Xenix termcap and Xenix and System V terminfo man pages all say that
"cl" homes the cursor.
(2) If it doesn't, then why do even BSD termcaps (so you can't argue that SV
!= BSD, which is irrelevant anyway because all SV termcap stuff comes
from BSD; AT&T endorses terminfo, PERIOD) output BOTH sequences for
common terminals where it takes separate sequences to clear the screen
and home the cursor (ex: all DEC terminals)?
I think this argument leaks somewhat.
