This comment likely applies to .exp file, not .cc.  Besides, 
it would be better not to mix style changes with essential changes,
to simplify review.

Ah, and I've posted a patch to move most of .exp into .cc file,
so I guess we've mid-air collision.

Am I missing something, or this change is not included in
your mail? Ah, I think it's the CVS problem, whereas added
files are not included in diff.

FWIW, once my "Simplified MI tests" patch is checked in, this block
can be just removed.

Looks good. I've poked at this manually and it seems to work like
it should.

Now I guess you need to post a patch including the C++ file changes,
now that it's in CVS, and we need to find somebody who can actually
approve the patch.
