Also, if I may, and as I may not have been clear enough earlier (as it
confused at least Martin): these "rolling" tightenings of "standards" and
tests are IMHO one the many rather clever "devices" R Core and CRAN use to
keep improving the quality of the code we all produce.  It's a good thing.

That said, and just like Terry, I have also searched many times for these
variables, and part of me thinks that it a crime that the material is spread
over (at least) three different manuals but _c'est la vie_. Until we get a
dedicated volunteer editor, or, deity forbid we decide to spend some
(collective) money on professional documentation.
