Personally I think it's just clutter, but hey, it's off by default. Of
course what is the chance that you've turned on status.showauthor in
your ~/.gitconfig, but you don't have your identity set up properly? :)
The point is that *someone else* can have showauthor set up in .gitconfig,
and then he'll be able to use git commit --amend to fix up
the identity without using --author explicitly.
For that you would need to update git-commit, I think.
