The joys of expect/tcl.  I just keep escaping until the regex that I 
developed outside the suite works.  I have been trying to get away from 
using .* though.  The longest match nature sometimes gives surprising 
results.  In theory .*? ought to work better, but I haven't tried using 
it much.

Anyway, the change looks fine to me.
