So, maybe the `rfc822' module should not accept it either.

A generic, encompassing, forgiving multi-format date recogniser could
likely try to grok such kind of errors and read a date nevertheless.
The `rfc822' module does not do enough in the direction of such a general
recogniser to be worth trying to subsume the role, it is not capable
enough.  This being given, the `rfc822' module would probably be more
useful being strict about what RFC 822 (or RFC 2822) dictates.
