I believe this, and a bit more, is in bug #15102.
The report hasn't been acted upon, but not been dismissed either, so
presumably there's general agreement that something is wrong, but
someone needs to check the suggested fixups in detail.
It's quite amusing how issues can go unnoticed for years and then be
reported by two different people within a week. Or is there perhaps
a more direct reason that the two of you should happen to be on the same page?
I am not sure how to find who authored the bug report but I have not
used reshape for a while and I found the documentation issue this
afternoon and so must assume this is just a coincidence. As I implied
originally I do not think it is a bug, more of an undocumented feature.
