[PATCH v3 0/2] add git-check-mailmap command

This is a re-roll of v2 [1] which introduces git-check-mailmap. The primary motivation for this command is to expose git's stable, well-tested C-implementation of .mailmap functionality to scripts and porcelains, thus relieving them of the need to re-implement support themselves. The git-contacts [2] script (currently at es/contacts in 'pu') would be one such client.

v3 addresses comments from reviewers [1].

Changes since v2:

* Drop -z/--null option.

* Simplify grammar of DESCRIPTION and OUTPUT sections of
  Documentation/git-check-mailmap.txt.

* Normalize wrapped code indentation to match standard Git style.

* Drop v2 patches [3/4] and [4/4] which convert t4203-mailmap.sh to test
  low-level mailmap functionality directly via git-check-mailmap rather
  than indirectly via git-shortlog.
