Summary
When O_NOFOLLOW is specified and the target is a symbolic link FreeBSD
sets errno to a value different to that specified by POSIX.  A note to
this effect was added in commit 295159dfa3ed, but I missed it when
reading through the list of errno values.  In the errno list, add an
explicit note and reference to the note in the STANDARDS section.

Ah, there is some debate on that topic, but mandoc does indeed suggest it not be used. I just copied it from the existing .Tn POSIX below, and wouldn't object to a pass over e.g. all of libc's man pages.
