I've gone through the initial patches, and stopped before the tests
(which I usually can't be bothered to review anyway).
The comments I have a relatively minor and could be applied as fixes
on top if Oliver can be convinced to do so. Note that patch #4 has an
attribution issue.

Can you please make an effort to base your postings on a known, stable
commit? A tagged -rc would be best. but certainly not a random commit.
This sort of information is just as useful as "No functional change
intended"...
