While the additions themselves nominally look good, all being extensions
they ought to be gated by the appropriate ifdefs, and the manual would best
mention what gates are needed to get them.  %q would be __GNU_VISIBLE as
the gate and _GNU_SOURCE for the user/manual, and I'd guess probably
__MISC_VISIBLE gate for the others (user action as noted in sys/features.h).
