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. ) > Ingo is 'missing' most of the time, so while I sit here with a > massive queue of patches its nearly impossible for me to get > anything merged :-( 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, Ingo
