Oh yes. 
Anyone who uses nl for documents will need it.
That includes autogenerated source documentation with page numbers.
(IIRC, MIT's xv6 uses it this way).
That means add -d, -f, and -h.
Also -i is useful; I thought I heard that dash or some other shell with a BSD
ancestry used -v in its buildscripts, but could be wrong.
Full POSIX is "pb:d:f:h:i#l#n:s:v#w#".
