ls-files: optionally recurse into submodules
Allow ls-files to recognize submodules in order to retrieve a list of files from a repository's submodules. This is done by forking off a process to recursively call ls-files on all submodules. Use top-level --super-prefix option to pass a path to the submodule which it can use to prepend to output or pathspec matching logic.
