[PATCH 0/3] recursive support for ls-files

After looking at the feedback I rerolled a few things, in particular the --submodule_prefix option that existed to give a submodule context about where it had been invoked from. People didn't seem to like the idea of exposing this to the users (yet anyways) so I removed it as an option and instead have it being passed to a child process via an environment variable GIT_INTERNAL_SUBMODULE_PREFIX. This way we don't have to support anything to external users at the moment.

Also fixed a bug (and added a test) for the -z options as pointed out by Jeff King.

Brandon Williams (3):
  submodules: make submodule-prefix option an envvar
  ls-files: optionally recurse into submodules
  ls-files: add pathspec matching for submodules
