Subject: [PATCH 1/3] Add regression test for RFC850 parsing

Although not supported directly by chrono, users should be able to
specify the RFC850 format and expect it to parse properly. RFC850 is
important since HTTP/1.1 specifies

    HTTP-date = rfc1123-date | rfc850-date | asctime-date

Subject: [PATCH 2/3] Fix parsing LongWeekday for Sunday

Only `Sun` was consumed, and the string being parsed would have `day`
left over at the front.
