I've thought hard about this one.  I'm ok with the theory in that we 
should have a test of GDB against a "pipe" (i.e., something that doesn't 
echo).  I've reservations about applying it across all tests though.

At present you can look at the log and see the exact interaction as 
you'll get when you run that same GDB in a normal terminal.  This change 
alters that.

Can you post an example log so that we can see what it looks like.
