[PATCH 00/22] mailmap: doc + test fixes

Just a "small" addition to v1, now with 21 extra patches. While this is a large series, it should be relatively easy to read and non-contentious. Mainly

 * We now have a "man 5 gitmailmap", rather than including the format
   description in N places.

 * Lots of extra tests & improvements to modernize existing tests to
   make them more reliable and easier to read.

 * Rewrote the example section in the documentation to be more
   understandable, and you can now follow it along with tests that
   mirror it.

 * Document that mailmap name/email matching is case-insensitive.

 * Document & test for the comment syntax.

 * Add an "--author" and "--append" argument to test_commit, which is
   used by the mailmap tests, but also a few other tests (just as an
   example). This is why the series modifies a few non-mailmap tests.
