The commands

http::data
http::status
http::code
http::ncode
http::size
http::error
http::cleanup

are all documented, public commands of the
package http.  They should be added to the
[namespace export] list.

Also, the command

http::mapReply

has the form of a public command.  It should either
be documented and [namespace export]ed, or should
be changed to look like a private command.
