Oh, so it is.  Hmm, I seem not to have checked that bit, sorry.

Perhaps the presence of the termcap file is irrelevant, or could it be
that nano used to be able to make use of that, and more recently only
supports terminfo?

Well, ncurses-base provides /lib/terminfo/x/xterm (in normal .deb
packages), so perhaps that's why, although AFAICS it wasn't including
that file in the udeb, even when things were working.

Making it ship a terminfo for xterm in the udeb would probably fix
things, but I think it would also be quite nice to know why it broke.

Cheers, Phil.
