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.
