Re: [PATCH] pretty: lazy-load commit data when expanding user-format

I added the final test to show where we don't improve (the 1% there is
just lucky noise), but also as a regression test to make sure we're not
doing anything stupid like loading the commit multiple times when there
are several placeholders that need it.

This benefits "rev-list --format=", as well, though there you can also
use things like "--parents" instead, which are already fast.

Quite pleased to see more work lazily done (and personally I am
happy to see Michael's name on the list---say Hi, I missed him).
