[PATCH] Nice error message for empty idents

[Petr Baudis <pasky@suse.cz>]

Dear diary, on Sat, Feb 18, 2006 at 09:44:14AM CET, I got a letter
where Junio C Hamano <junkio@cox.net> said that...

One dislike from me - you shouldn't care if you ain't gonna do it - it
makes no sense to require valid gecos if you are never committing
anything. Note that this "premature requirement" plague has already hit
GIT - come on:

	$ git-rev-list --help
	fatal: Not a git repository

That's worse than CVS (which allows cvs --help cmd but not cvs cmd
--help outside of a repository).

I agree that the error message itself is bad.
