Re: [PATCH] Fix 'git commit -a' in a newly initialized repository

[Junio C Hamano <junkio@cox.net>]

If we want to limit the help to lone liner, I am with Nicolas and
Fredrik on this one.  Suggesting only "git add ." does not feel
helpful.

However, because ! test -f "$THIS_INDEX" is such a special case
(totally new check-in), we can afford to be verbose if we wanted
to, and offer tons of possibilities, say:

	die 'nothing to commit.  You can use "git add file..."
to include individual files, or use "git add ." if you want to 
include all files in the current directory, for your first
commit.'

But if we want to say "for your first commit" in the message, we
should also be checking if HEAD commit really does not exist.
