Confusing exports and documentation of http_reply and http_status_reply

[spl]

There are a number of inconsistencies between what's exported, what's documented for the predicate, and what's actually defined for http_reply and http_status_reply in http_header.pl.

Also, note that Status is mentioned in the docs for http_reply but doesn't show up in the documentation.
