[PATCH v4 0/6] submodule: drop the top-level requirement

Changes since v3:

* There are four new patches, three of which are style fixes for
  existing tests and one fixes an existing error message to return a
  more accurate path when recursing.

* You now cannot run "git submodule add <relative URL>" from a
  subdirectory.  Because the interpretation of the URL changes depending
  on whether or not remote.origin.url is configured, I have decided to
  just ban this for now.  If someone comes up with a sensible way to
  handle this then we can lift this restriction later.

* The "path" variable exported in "submodule foreach" now uses the
  relative path and matches the "sm_path" variable.

* I audited the code again and fixed a few more cases that weren't
  printing relative paths (notably "submodule init" and "submodule
  foreach").

* More tests.
