Well ... the problem is that the global inbufflags == INP_ALIAS which
means the shell believes it is still expanding "foo".  This causes it
to zero out everything when hbegin() is called, instead of allocating
a new chline etc., so when hend() is finally called ... boom.

What I don't follow is why inbufflags isn't getting cleared properly
on send-break ... because I can't figure out where it's ever cleared
at all.  I'm not very familiar with teh flow of control in input.c.
