Good detective work, Peter. So is the bug in FreeBSD or Emacs? The
new man page for tgetstr says:
Bugs
If you call tgetstr to fetch ca or any other parameterized
string, be aware that it will be returned in terminfo
notation, not the older and not-quite-compatible termcap
notation. This won't cause problems if all you do with it
is call tgoto or tparm, which both expand terminfo-style.
Emacs tries to expand the string itself rather than by calling tparm
and we've surprised it by returning the string in terminfo style
rather than termcap style.
Here's an alternative patch that forces Emacs to use the library
versions of tparm and tgoto to do the decoding rather than rolling its
own. Put this in /usr/ports/editors/emacs20/patches/patch-ce
(although it really should get merged into patch-ca). It works by
using the module intended for Emacs running on terminfo machines
(ie. it uses terminfo.c rather than tparam.c). I tried this (briefly)
on -current and -stable and it seems to work ok.
