As a matter of fact, all my xterms have "COLORTERM = gnome-terminal", so
the above ends up running even though I'm in a plain uptodate xterm
rather than in a gnome-terminal.

This is probably not the usual situation (it's a result of some silly
way I log in), but it does point to the fact that xterm itself does not
reset COLORTERM, so it's not a reliable indicator.
