Of course it _is_ a range; didn't you read it in the "specifying
ranges" section?  It is a short-hand for "include HEAD, exclude its
parents", and you can further combine it with other starting points.

Sounds like a bug, if it doesn't.

Patches welcome---I suspect that it can be solved the same way as
the recent cherry-pick patch by Miklos.

That is why I said this is "git log", not "git show".
