Okay, so what I hear you saying is that commit c45dc7ffb needs to remain
in the release notes, but its description sounds like 27b62377b4, which
was reverted, so my description is wrong for c45dc7ffb.

I would love to blame the patch revert on this mistake, but looking at
the history of this entry, I just didn't understand it when I initiallly
wrote it.  Updated applied patch attached.
