I'm not 100% sure that this is the right fix but the new snapshot at
least works around the problem.

The problem is that screen explicitly sets VERASE to 0.  I believe that
it does that to mean "there is really no erase character since I'm
handling that".  That should not cause Cygwin to send a null character.
I think it should probably just send the default \177 character.

So that is the change I've made.
