That's not always true.  Some systems have a libtermcap which is merely
libtermcap, not some sort of (n)curses termcap emulation.

No, the original point of this was to link the termcap module with
whatever has tgetent() and the terminfo module with whatever has tigetstr().
On Debian, for instance, they're both covered by ncurses, but elsewhere
there can be conflicts.

No, I clearly don't know what I'm doing or I would have gotten it right
the first time.

Originally, you would only get the terminfo module if whatever
library selected for termcap also did terminfo.  This was, IIRC,
because people didn't want terminfo libraries linked against
the main binary just for the sake of a module that they would
not use.  Obviously that's gotten more complicated now.

I had started this and then lost my changes due to a system crash,
but I'll restart it soon.
