[PATCH v4 0/2] grep: add fallbackToNoIndex config option

Previous rounds are at $gmane/283619 and $gmane/283670. (Gmane seems to lag behind, I can't seem to find v3 there). Thanks to Peff for the review of the previous round.

Changes since the previous round:
  - removed unnecessary call to setup_git_directory_gently()
  - reverted the change to the error messages, as the originals should
    provide enough information to the user.
