One extra comment.  I though of making the watchpoint trigger only
exactly in the frame where the condition was set, so to
conditionalize on a particular local instance, but I thought that
if the user wants that behavior, he can emulate it by:

 (gdb) p &local
 (gdb) watch global if *$ > 10.

But there's no way to emulate what the patch allows, and
it seemed intuitive, so went with it, and so the user can
have it both ways.
