I didn't say the "terminfo" approach was necessarily the right one.  I
merely pointed out - correctly - that the flexibility you get from
"termcap" is not an unmixed blessing (as you've already discovered,
given your comment that 1) "RI" isn't in the manual for your Ultrix
system and 2) the fact that there's this "ch" capability that doesn't
quite look right)....
