How about doing it this way instead, then?
Saying "fatal: You haven't made a commit?" is like saying "How stupid do
you have to be to realize that you are not allowed to run git-log before
making a commit, dummy?", but that is not the message we need to be
sending. Asking for log is fine. If you are on an unborn branch and say
"git log", you deserve to get nothing. Not even an error message.
Not that I haven't thought through the ramifications of this yet; some
callers may need to be adjusted, but they should be prepared for a case
where no rev was given from the command line anyway.
