Yes.  At the time I wrote it it was unclear what the status of the
original patch was (whether it would be applied sooner vs. later).  At
this point it seemed expedient to continue to keep the patches
separate since they had been reviewed and tested separately.  Earlier
I made the offer to combine and re-spin and I'm happy to do that if
requested.
