Yeah, I struggled with that text for a bit.  It doesn't seem to make sense
to explain that n means the n'th occurrence of a particular d value before
we've explained what d is, so explaining the fields in their syntactic
order seems like a loser.  But we could describe m first without that
problem.

Not sure about replacing the m/n/d notation --- that's straight out of
POSIX, so inventing our own terminology might just confuse people who
do know the spec.
