[PATCH 0/4 v4] recursive support for ls-files

[Brandon Williams <bmwill@google.com>]

A couple things have changed in v4:

- Restructured the patch series to prevent a breakage mid-way.
- Added an additional patch in the middle to pass through safe options.  This
  way the series is structured in a more coherent manor.
- Added --submodule-prefix to top-level git.c

Hopefully this series addresses some of issues brought up in v3

Brandon Williams (4):
  submodules: make submodule-prefix option
  ls-files: optionally recurse into submodules
  ls-files: pass through safe options for --recurse-submodules
  ls-files: add pathspec matching for submodules
