Yeah; someone mentioned that rxvt, while it uses TERM=xterms, defines
some extra environment variables.  I just checked, and I see these:

   # black-on-white rxvt (the default)

   # white-on-black rxvt (rxvt -fg white -bg black)

   # green-on-black rxvt (rxvt -fg green -bg black)

Not perfect (it would be better to actually get the terminal's whole
colormap in absolute terms) but that seems enough for emacs to do a
decent job of setting up the background type at least.

So I think Emacs could use the above information if it's present, which
will cover rxvt, and as you say, submit a patch to make xterm define the
same variables.

[An additional variable giving the whole colormap would be even nicer,


Maybe we could try to submit a patch to export that info too...]
