I'm actually a bit confused that Barry changed the meaning of "build
number" for that feature. The build number was meant to count builds,
not revisions (whether this is a useful feature or not).

So I would argue that it is "broken" when it is the result of
svnversion, and "good" when it actually counts builds.

It stopped counting builds on Windows quite some time ago; perhaps it
is best to drop the build number entirely?

Propose first. I have the feeling that the feature will change forth
and back if everybody gets to say something. I would call it
sys.svnversion (because that's what it is).

What to put in in case of tagged builds is then yet another question.
