[PATCH v3 0/5] Teach mv to move submodules

[Jens Lehmann <Jens.Lehmann@web.de>]

Here is my third iteration of this series.

Changes to v2 are:

- I resolved the conflict with Duy's pathspec series by replacing the
  use of common_prefix() with relative_path().

- I separated the functions checking for modified unstaged .gitmodules
  and staging the changes to that file into another commit, as they
  are used by both mv and rm.

- mv and rm now die with the message "Please, stage your changes to
  .gitmodules or stash them to proceed" instead of changing and
  staging a .gitmodules file containing other unstaged modifications.

- Man pages for mv and rm are updated to tell the user what they do
  with the gitlink and the .gitmodules file in case of submodules.

- Minor changes according to the last review (typos and a bit more
  efficient coding).

This series applies cleanly on current pu (and I also ran t3600 and
t7001 manually to make sure I don't hit the silent breakage my last
series showed when I ran the whole test suite).
