[PATCH v3 1/4] doc: move author and committer information to git-commit(1)

["brian m. carlson" <sandals@crustytoothpaste.net>]

While at one time it made perfect sense to store information about
configuring author and committer information in the documentation for
git commit-tree, in modern Git that operation is seldom used.  Most
users will use git commit and expect to find comprehensive documentation
about its use in the manual page for that command.

Considering that there is significant confusion about how one is to use
the user.name and user.email variables, let's put as much documentation
as possible into an obvious place where users will be more likely to
find it.
