Please forgive my ignorance, I've been reading online as much as
possible to understand tcl/expect ...

I understand how anchors work, however, I didn't realize you could start
matching in the middle of what the 'buffer' is. If it started matching
after it, does that mean it's skipped forever? So basically, you can
match a subset of the output, and the rest is lost (never matched)?

If that's the case, the testsuite for the MI is matching even less than
I thought. GDB could output almost anything, but then just have to match
the last string, and the testcase would pass, correct?
