Whoops. I even got it right in the similar line above. :-/

This did make me wonder how the whole thing fares on a system where
"unsigned long" is 32-bit (AIUI, Git for Windows is such a system).

The sizes passed around (here and all through git) are "unsigned long",
so I don't think we're making anything _worse_.
