But you're explicitly *using* the configured setting in

  git config --file $toplevel/.gitmodules submodule.$name.branch

That should be a reminder that the configuration is important, and
you'll remember to change it.  Plus, the text from git-pull should
clearly display the branch you are pulling, which gives you a second
change to notice if something is going wrong.

All of these are possible, and all would reqire manual intervention to
pick out a new branch to follow.  Plus, this patch is not even about
the auto-pull application, it's about storing the initially cloned
branch name.  What you do with that name afterwards is up to you ;).

Interesting.  What would you attach the note too?
