	Actually not sure I can reproduce this now.  The only
thing I am noticing is that if bash is attached to /dev/pts3
(as in mintty), it works, but if attached to /dev/cons0 (as in
cmd.exe), nothing works as no signal is propagated from
the window resize to running program.

	AFAIK, though, that's always been one of multiple 
probs in using windows cmd with a bash shell.
