Side note: sometimes you might want to use a different key than the one you use for authorship. Then you can use

	[user]
		SigningKey = key

(or "git config user.signingkey xyz" if you don't want to edit the config file manually).

This can be especially useful if you use different keys for different projects, even if you want to be known under the same name in both. Or because you want to have the local hostname in your commit logs, but your gpg key is using some externally visible "official" email address.
