Date reference typo

[mnot@…]

Currently, RFC2616 says about the date format for the "Date" header:

"The field value is an HTTP-date, as described in section 3.3.1; it MUST be sent in RFC 1123 [8]-date format."

Proposal: "The field value is an HTTP-date, as described in section 3.3.1; it MUST be sent in rfc1123-date [8] format."

Fixed in [83] and [100]. However, the fixed wording remains problematic in that the MUST requirement has no basis in reality.

See related design issue #51 for tracking the MUST requirement.
