The current (and planned) implementation of git-submodule detaches
HEAD in the submodules, so there will not be a current branch unless
the user has done 'cd $path && git-checkout somebranch'.

We might take advantage of that fact:
  * try to exec 'git-symbolic-ref HEAD'
  * if it fails, push to path.$path.branch
  * otherwise, push to the ref pointed to by HEAD

But this will still loose any changes on _other_ branches (that has
not been pushed to origin manually). I'm not sure if/how we can avoid
this, except by making $path be a symlink to .git/submodules/$name.git
(which has other issues...)
