bug#10683: 23.4; Reverse video doesn't work for -nw

[lmi]

I just upgraded to 23.4 and suddently background is white and text is
black.  On IRC I've been told to set-background-color to whatever I
like, which is awesome (after you realise that you stop seeing anything,
because letters are black now too, and you don't know where the cursor
is, because it's black as well).  However, I'm not using X, only -nw, which used
to support transparent background just like that, now it seems it is
doesn't anymoar, because apparently one cannot unset background colour.
