Log message:
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).
