Oh, that's even worse, since the safety valve doesn't kick in when it
should. For example, with what's in next now, I can do this:

  git checkout v1.4.0
  hack hack hack
  git commit -m -a 'some changes which will never be seen again'
  git checkout v1.2.0

I thought the _point_ of the safety valve was not to lose those changes.

As Carl mentioned, I think recommending that workflow is a terrible idea
from a user interface perspective.
