[PATCH v2 0/3] Document git-submodule's default behavior

Thanks for the suggestion, Duy.

While I was fixing that up, I noticed a few other discrepancies so I decided to fix those up too.

Changes since v1:

* Incorporate Duy's suggestion of "The default command is '...'"
* Fix additional discrepancies between git-remote and git-submodule (on the
  submodule side)

Denton Liu (3):
  git-remote.txt: be specific about default behavior
  git-submodule.txt: make subcommands underlined
  submodule: document default behavior
