After some constructive criticism from pjanzen@ and some e-mail tag:

   - only use the .Dv NULL form when referring explicitly to a function
     argument or return value
   - otherwise, use these forms:
        o non-null
        o null-terminated (hyphenated form for predicate adjective)
        o else, null terminated, or null terminate, whichever the case
        o null pointer, null byte, null string, etc.
   - may use NUL to refer to an ASCII NUL, but it doesn't need a .Tn macro

In general, capitalizing the word "null" everywhere is unnecessary and makes
the man pages harder to read. The above is consistent with popular programming
texts (i.e., K&R, Stevens).
