[PATCH 0/3] Convert grep to recurse in-process

This series utilizes the new 'struct repository' in order to convert grep to be
able to recurse into submodules in-process much like how ls-files was converted
to recuse in-process.  The result is a much smaller code footprint due to not
needing to compile an argv array of options to be used when launched a process
for operating on a submodule.

Brandon Williams (3):
  repo_read_index: don't discard the index
  setup: have the_repository use the_index
  grep: recurse in-process using 'struct repository'
