[PATCH 0/3] get_maintainer: add patch-only keyword matching

[Justin Stitt <justinstitt@google.com>]

This series aims to add "D:" which behaves exactly the same as "K:" but
works only on patch files.

The goal of this is to reduce noise when folks use get_maintainer on
tree files as opposed to patches. This use case should be steered away
from [1] but "D:" should help maintainers reduce noise in their inboxes
regardless, especially when matching omnipresent keywords like [2]. In
the event of [2] Kees would be to/cc'd from folks running get_maintainer
on _any_ file containing "__counted_by". The number of these files is
rising and I fear for his inbox as his goal, as I understand it, is to
simply monitor the introduction of new __counted_by annotations to
ensure accurate semantics.

See [3/3] for an illustrative example.

This series also includes a formatting pass over get_maintainer because
I personally found it difficult to parse with the human eye.
