The $branches is from Denton's script (its in his email that I replied 
to) that lists all the branches merged into git/git-gui that are not in 
git-gui. So it should essentially be all the branches not in my tree 
that should be.

No, I was only pulling in merges related to git-gui into my tree. I do 
not intend to pull in any other changes.

Yes, that is what I was doing. Denton's script just made the tedious 
task of finding all those out easier.

Well, technically it won't be a noop merge because my master has some 
changes that haven't been pulled by you yet, but I get the point. 
Thanks. I'll test this out.
