-- (This came up as a side issue when looking into details of bug #15483; it's not directly related, so filing as a separate report.)
There's a FAQ put out by opengroup.org
http://www.opengroup.org/austin/papers/posix_faq.html
which remarks (Q10) that "a POSIX.2 standard no longer exists". Should
grep.1 [2.14] (which refers to POSIX.2 in several places) be updated to refer
instead to "the Shell and Utilties volume of POSIX.1-2008"? Or perhaps just
"POSIX.1"?
