Yes. There's nothing *technically* wrong with an empty commit. The reason 
"git commit" doesn't do it is that it's just almost always a mistake.

If you know ahead-of-time that the tree is HEAD, there's no reason to do 
the "git-write-tree". You can just use "HEAD^{tree}" instead (and in 
fact, I think git-commit-tree will happily just take HEAD directly).

And please give a log messages for "git-update-ref"

Please do make sure to do some of the other sanity checks that "git 
commit" does, though. It is a good idea to at least verify that the commit 
message isn't empty etc.
