That's one way. You could also check TERM, which will be different in
those two environments. Personally, I'd check the tty you are on:

	if (`tty` =~ /dev/ttyp*) then
		exec bash
	endif

Of course, all three of these tests give different behavior if you're
on something other than the console or an x terminal emulator of some
kind.
