Absolutely.  

I think we three are on the same page now ;-)

Now one issue I am not so sure about is if the only thing that needs
adjusting is branch.*.remote + branch.*.merge.

The open-ended nature of our design means it is _possible_ to be
reasonably sure to have covered everything we do in the core part of
Git, but it is certain for us to miss third-party enhancements.

An inevitable "why not do all that when 'git branch -r -m old new'
is given?" posed by those who are not aware of the design needs to
be shot down, which is unfortunate.
