git-commit.txt: better description what it does

The description of git-commit jumps right into the commit content, which
is important, but it fails to mention how the commit is "added" to the
repository. Update the first paragraph saying a bit more about branch
update to fill this gap.

While at there, add a couple linkgit references when the command is
first mentioned.
