When committing for someone else, using the --author option, it can be
nice to use the mailmap file to find the correct name spelling and email
address.
Currently, you would have to find the correct mapping in mailmap file
first, and then use the full ident form when committing.
Let's allow git-commit to find if an entry exists in mailmap file for
that pattern, and use that instead.

Hi,
I would use that feature at work where I happen to commit some work for
other colleagues, while we heavily rely on mailmap file to have decent indents.
On the other hand, I'm kind of embarrassed to add this new option to
git-commit.
