Subject: How can I create a commit without a parent?
Message-ID: <ron1-5383E3.00002602022010@news.gmane.org>

SLSIA.  git commit-tree insists on having at least one parent commit at 
the command line.  From reverse-engineering it seems like I could do it 
by setting .git/HEAD to 'ref: refs/heads/some-nonexistent-branch' but 
mucking with HEAD directly like that feels kinda scary.

Thanks,
