[PATCH v2 0/9] Improve handling of moving and removing submodules

Changes since v1:
 - Generate a more user friendly unique ID
 - Added tests for "git rm" error cases (thanks Jonathan Nieder)

Peter Collingbourne (9):
      Generate unique ID for submodules created using "git submodule add"
      Implement "git mv" for submodules
      git rm: test failure behaviour for multiple removals
      git rm: display a warning for every unremovable file
      git rm: collect file modes
      Add a mode parameter to the remove_path function
      git rm: do not abort due to an initialised submodule
      git submodule: infrastructure for reading .gitmodules files in arbitrary locations
      git rm: remove submodule entries from .gitmodules
