... It implicitly enables signing, since it doesn't make any
sense without it. Thus:
	git tag -u <gpg-key-name> <tag-name> [<tagged-object>]
will use the named gpg key for signing.

This is important for another reason as well: a lot of people have 
multiple keys.

Agreed.  Thanks both.  Will apply.
