[PATCH 0/3] push only submodules

[Brandon Williams <bmwill@google.com>]

This series teaches 'git push' to be able to only push submodules while leaving
a superproject unpushed.

This is a desirable feature in a scenario where updates to the
superproject are handled automatically by some other means, perhaps a
code review tool.  In this scenario a developer could make a change
which spans multiple submodules and then push their commits for code
review.  Upon completion of the code review, their commits can be
accepted and applied to their respective submodules while the code
review tool can then automatically update the superproject to the most
recent SHA1 of each submodule.  This would eliminate the merge conflicts
in the superproject that could occur if multiple people are contributing
to the same submodule.

  transport: refactor flag #defines to be more readable
  submodules: add RECURSE_SUBMODULES_ONLY value
  push: add option to push only submodules
