Thanks for digging this through before I got to it. Very much appreciated,
and sorry or the mismerge (incidentally this was why I wanted to merge
early these two topics that tried to improve different things that
happened to touch the same part of the code, as I knew such a merge was
risky and needed plenty time before it hits released versions).
