[Patches usually go to xorg-devel@, not xorg@, for review/submission.]
The greybeard in me wants to suggest that hardcoding the escape codes
is wrong and that termcap/terminfo should be used instead to find the
right ones for $TERM, but the realist in me wonders if there are any
$TERM values in widespread use these days other than xterm, screen,
and various vt100-variants.
