right. this is useful, but more useful is finding out whose code went
into a *specific* version of a file. One you know who the guilty one is,
then you usually want to drill down to see whether they created the code
or just modified it, whether it was correct before they touched it, etc,
etc.

but i'm just talking about the top level interface. "who's the last person
to touch this line of code". and usually there i *don't* want to know
about reverts, because they didn't actually "change" the code.
