Geert,

I think I had a brain-fart. I was thinking of `checkout -b release-1.8.0`, which will sometimes fail to do what you want (make a tracking branch when there's a corresponding origin/release-1.8.0. branch; it never works with tags, of course). Without the '-b' it will of course checkout the tag. Sorry.

While we're on the subject of git, you turned off travis builds on the trunk branch, but we kept that around to make life easier when we moved away from svn. Maybe it's time to just remove it?
