The NEWS for R-devel has the following item:
The previously included versions of zlib, bzip2, xz and PCRE have been removed, so suitable external (usually system) versions are required (see the ?R Installation and Administration? manual).
Therefore I believe the following information in 'src/library/base/man/regex.Rd' is no longer valid:
If PCRE support was compiled from the sources within R, the PCRE version is 8.36 as described here.
Not quite. It is still *valid* : every statement about the
elements of the empty set are true, in the same sense that
if (FALSE)
"something or other"
is never invalid, but of course, that information should still
be removed because indeed, it is empty.
Help pages are not intended to be just about the current version of R but also recent versions, and most builds of 3.2.x will meet the condition. However, as from 3.2.0 a user can find the version of PCRE in use by extSoftVersion, and I have added a comment about that, including for 3.2.3.
Thank you Mikko!
(and excuse the completely unnecessary pickyness ;-)
