Sorry for that. I failed to consider that your work was applying there as well.

Ok, I see what you mean -- but I suppose that's the kind of
information that would be nicely abstracted out somewhere. At least I
would put it in a sub. And that sub would fit perfectly in your
caching module, too! Looking at the source, a generic git-rev-list
wrapper could be used.

If you want I can produce a patch against your version, but I'm afraid
I'll end up being a bit short on time, so I might be slow to do it.

Ok, noted. Also, next time, I'll send smaller patches.
