Right, that was my thought: though perhaps not technically as precise, it is much more DWIM.

My other concern, which I failed to voice in the original mail was: should we do this magic for other reflog entries besides the first one? It is possible to end up with a null sha1 in any other entry? Branch creation shouldn't do it, because we will have deleted any previous reflog when killing off the branch before, so we always end up putting in the "oldest" reflog entry. Cloning shouldn't do it for obvious reasons.
