I merged it, but then it broke and I reported the breakage - and
zapped the bits to not create dependencies on broken bits.
( There was also quite some discussion back and forth as recently as
two weeks ago, so it didn't feel cooked enough to me to pick it up
directly from email - but once it shows up in your queue I'm picking
it up. )

Right now I'm somewhat 'missing' because I fell ill right when the
merge window began :-/ But I merged all your pending bits shortly
before the merge window started. During the merge window itself I
try not to merge fresh patches.
Thanks,
