I actually have a patch pending to mention one specimen of that cap-code
("short name") style in curs_termcap.3x.  This arose because its C
symbol name (long name) was already under discussion.

I'll be sending along a fairly substantial chunk of proposed man page
patches, plus a couple of bonus bug fixes, later today or tomorrow.
