Catching up on bugs

[Graham Percival]

With the release of 2.13.9, we now believe that all bugs are
either fixed, or have been added to the issue tracker.  If you
have reported a bug and it is not in the tracker, please check the
bug reporting guidelines and re-submit it.

Valentin, James: I think it's time for the annual "checking the
regression tests".  Instructions are in the Contributor's Guide
6.4 Checking and verifying issues.  I'll let you two decide who
does what.  It would be nice if this was done within a week or so;
it's not a huge job.

After that, we'll have 2.13.10, and then you two can start
checking all issues.  There will be more specific guidelines about
tagging and priorities.  I'm going to collect my thoughts into
specific proposals, and begin discussions later today or tomorrow.

Cheers,
- Graham
