The current system is to have a `stable' branch always pointing at the
most recently released version of the repository.  Then on releases a
`release' branch is made up based on `master'.  When the release is
done, `stable' is advanced to the point where `release' is, but this
is done in an explicit way that makes it point to the previous
`stable' as a parent -- so the two lines (`master' and `stable') are
kept in parallel.  This is why `git describe' looks weird -- as
Matthew said, it just finds some tag in the past that happens to be
the last one before this was started.

This was done due to some problems with 3rd party packages who follow
the repository -- I don't remember the details, but David Bremner was
the one pointing at the problem so he might be able to explain it.
(And if there's no problem, then it is probably better to not do that
