[PATCH v3 0/3] use mailmap by default in git log

[Ariadne Conill <ariadne@dereferenced.org>]

It is not uncommon for people to change their name or e-mail address.
To facilitate this, Git provides support for the `.mailmap` file,
which contains a list of identities and previously used e-mail
addresses that are associated with that identity.

Unfortunately, while Git's support for the `.mailmap` file is generally
excellent, I recently discovered that `git log` does not treat the
mail map file the same as the other tools, instead requiring an
explicit flag to use the mailmap file.

I believe this is an unfortunate flaw, as the mailmap file should
ideally contain the most current known contact information for a
contributor, allowing anyone to contact the contributor about their
patches in the future.

New in version 3:
- Rework many mailmap tests to drop redundant `--use-mailmap` and
  more rigorously test --no-use-mailmap and configuration variants.
- Typo fixes in the commit messages.

New in version 2:
- The `--no-use-mailmap` option, which complements `--use-mailmap`.
- Tests for `--no-use-mailmap`.

  log: use mailmap by default
  log: add --no-use-mailmap option to complement --use-mailmap option
  tests: rework mailmap tests for git log
