Well, if you want precise definitions, here's the official text:
http://tools.ietf.org/html/rfc2119
Specifically:
1. MUST This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification.
[...]
3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
So, <998 columns is a MUST. <=78 columns is a SHOULD.
