 OpenBSD and FreeBSD have a man page for this. Can we take it from
 either of them?

 Yes, we usually take libc stuff from FreeBSD.

 Does this look fine? Mostly based on the FreeBSD man page. (I will add
 set entries for wcsnrtombs.3)

 FreeBSD man page also says that these functions may have EINVAL as a
 possible error but I am not sure if our implementation does that or
 not, so left that part as it is.

 A bit sibylline but I think that's correct. I guess that the original
 FreeBSD man page meant: `is an extension to the ISO C standard.' in this
 context (both in NetBSD man page, FreeBSD man page and Abhinav's patch
 the STANDARDS section does not reference `IEEE Std 1003.1-2008').

 Or, am I missing something?
