These warnings appear to be caused by:
commit 305701e856baa0b23066279160eaeb38bd27b9e4

contrib/hdtbl: do forgotten renamings .pv -> .t*pv
This was forgotten in commit 6fb4a0ab on Feb 8, 2010.
Fixing it improves the formatting of all hdtbl examples.
Reported by Bjarni Ingi Gislason in http://savannah.gnu.org/bugs/?54470.
While here, also fix a typo in short_reference.roff.
If I revert it, these warnings go away.

Yes; as I noted at the beginning of the thread, we're stuck with .psos
in hdtbl's examples until some refactoring is undertaken.

Depending on what you mean by "older", I can't reproduce that; if I
revert all 3 of Ingo's hdtbl commits from August, all of the examples
look good on my machine.
git checkout 7b3fa85e0f2da11f9475d2a36bb1a9608a6a999f
is a quick-and-dirty way to confirm this. (I would do that in a dummy
checkout; thanks to the gnulib submodule, it's mildly irritating to get
the tree back out of "detached HEAD" state.)
