- I've pushed 0003 - although that commit seems to have included a lot
  of things unrelated to the commit message. I guess two patches have
  accidentally been merged?  Could you split out the part of the changes
  that was mis-squashed?
- I've pushed an extended version of 0001.
- I've pushed 0002, after some minor polishing
- I've pushed 0004
