I don't mind at all.

I think my name is plastered all over "git log" enough as it is.

This function name is a bit weird. I would have thought the "from" here
was going to be a file, or a string, or whatever. But the filename setup
happens outside this function (and yet this function depends on it being
set up, as it calls git_parse_file). But maybe it will get less
confusing with the other patches on top...
