[PATCH v4 0/3] Teach submodule set-branch subcommand

[Denton Liu <liu.denton@gmail.com>]

Thanks so much for the feedback, Junio. I've updated the patchset based
on your comments.

Currently, there is no way to set the branch of a submodule without
manually manipulating the .gitmodules file. This patchset introduces a
porcelain command that enables this.

Changes since v1:
	* Fixed incorrect usage of OPT_CMDMODE

Changes since v2:
	* Corrected missing argument for -b/--branch in git-submodule.txt
	* Rebased onto latest next

Changes since v3:
	* Rebased back onto master
	* Address Junio's comments and improve clarity of submodule--helper patch
	* Fix incorrect documentation formatting in git-submodule.txt
