[PATCH 0/4] git-grep documentation updates

This patch series contains some small changes to git-grep.txt.  It is
based on my previous "grep documentation: clarify what files match",
committed to master as 3ac44408.  I posted these as four separate
patches to document each change individually, but they could be squashed
into one if that is preferable.

Mark Lodato (4):
  grep docs: pluralize "Example" section
  grep docs: use AsciiDoc literals consistently
  grep docs: --cached and <tree>... are incompatible
  grep docs: document --no-index option
