Merge branch 'bw/ls-files-recurse-submodules'

Browse Source 
"git ls-files" learned "--recurse-submodules" option that can be
used to get a listing of tracked files across submodules (i.e. this
only works with "--cached" option, not for listing untracked or
ignored files).  This would be a useful tool to sit on the upstream
side of a pipe that is read with xargs to work on all working tree
files from the top-level superproject.

* bw/ls-files-recurse-submodules:
  ls-files: add pathspec matching for submodules
  ls-files: pass through safe options for --recurse-submodules
  ls-files: optionally recurse into submodules
  git: make super-prefix option
