Hi,

In a recent email, I asked a contributor to help cleanup some 
ridiculously long expect regexps.

Eating my own dog food, I am going to be submitting some new MI 
functions which will facilitate regexp construction for breakpoints.

This patch simply removes a bunch of unused globals from mi-break.exp.
