Indeed, sounds good.

This should be in the ncurses package itself, since it is “owned” by
ncurses, not rxvt.
However, there’s the limitation that, currently, --search-paths
advertises the variables of things that are explicitly in the profile.
Ncurses is usually not in the profile; it is a dependency of something
that is in the profile. Thus, people wouldn’t see anything about
TERMINFO_DIRS in practice (we have the same problem with OpenSSL,
GStreamer, and other librairies that have associated variables.)
Long story short, I would avoid adding this ‘native-search-paths’ here,
but I’m OK with it since that would make the thing usable, provided
there’s a big FIXME in there.
WDYT?
