You were right; it was mutt. Even though no colours were specified, it
chose black on black for some reason. NVLC probably has the same
problem, but I can't verify it because the colour scheme can't be
changed. I'll try to talk with the people who maintain them.

Yes, it does make it (dark) red. I don't normally change it, though; I
use the default (which is reverse-video) plus blink.

Since the TERM values better supported by applications such as linux
and xterm require bce, I have to append ut to their entries in
./mlterm/termcap, otherwise coloured areas don't fill as they should.
Doing so, however, will trigger the aforementioned coloured cursor
glitch.

Actually, I think xterm's colorMode: 0 disregards all colour sequences,
including black and white. Since there's only one colour anyway (+ RV),
there's no need for them anymore, and they might also mess up some
things, so that's the way I think it should be done. It may or may not
disable other things like colour for attributes, cursor colour and so
on (I don't remember exactly how it works), but that's not important.

If there's no benefit to disabling colour at compile-time, then of
course there's no reason to do it. An option to ignore colour escapes,
however, would help in eliminating the coloured output that some apps
(mostly non-curses) output gratuitously, regardless of what TERM is.

Since I started fiddling around with those terminfos, I have (for one)
found out that plain monochrome (plus the various attributes) is very
pleasant, yet can still convey sufficient information. Removing the
distraction of coloured text in this case is, ultimately, a matter of
personal preference. Others may not like it (or may not care), but I
still think It's a good thing to have, at least for customisation's sake.
