[PATCH] push: change submodule default to check

[Stefan Beller <sbeller@google.com>]

When working with submodules, it is easy to forget to push the submodules.
Change the default to 'check' if any existing submodule is present on at
least one remote of the submodule remotes.

This doesn't affect you if you do not work with submodules.
If working with submodules, there are more reports of missing submodules
rather than the desire to push the superproject without the submodules
to be pushed out. Flipping the default to check for submodules is safer
than the current default of ignoring submodules while pushing.

 Probably too late for the 2.10 release as I'd propose to keep it in master for
 quite a while before actually doing a release with this.
 
 Thanks,
 Stefan
