Yes we agree, that's what we do. IT's a matter of investigating history.

I don't know any other way of putting this. I realize all of what you're
saying. But when debugging code, and I find a chunk changed in one file, a
way to quickly see when it changed is invaluable.

Maybe you're giving me a way to do that and I just am not seeing it. If I
binary search revisions, how is that done? You're saying I can diff revs 50
and 51 in a repository tree (for all branches/trunk etc) and see the changes
for all files, then pick out my foo.c and look at it? I've read the docs but
I can't see how to do it.
