Exactly. That is what I have set up now, except that I have to type "git
push peff" because there is no such push.default (with the minor nit
that push.default does something else, so the config should be called
remote.pushDefault or something). The entirety of the feature would be
saving the user from the annoyance of:

  $ git push
  fatal: remote error:
    You can't push to git://github.com/gitster/git.git
    Use g...@github.com:gitster/git.git

  [doh! Stupid git, why don't you do what I mean, not what I say?]
  $ git push peff
  ... it works ...

Right. Frankly, I do not care that much about the per-branch push remote
myself. In the rules I gave earlier, that was my complete
backwards-compatible vision, so that we do not paint ourselves into a
corner compatibility-wise when somebody wants it later. Just
implementing the default push remote part would be a fine first step.

I also indicated in my rules that we could have a branch.*.fetchRemote,
as well, but I do not think it is strictly necessary. I think the
non-specific branch.*.remote could continue to be used for fetching, and
as a backup when the push-specific variables are not set.

Right, I think "git pull" is more useful in a centralized repo setting
where there is one branch and one repo, so there is no "what and whom"
to specify. Personally I do not use it much at all, as I do a separate
fetch, inspect, and merge, but that is somewhat orthogonal to your
reasons. :)
