Fixed previous patch to reflect what Apache-1.3 did regarding self-

referential uri's, and updated the manual accordingly.
XXX There is a kludge here: XXX the port number from the client's Host:
header used to be tossed, and there is no clean mechanism to pass it
(in the request_rec) to other consumers. As the unparsed_uri structure
(which could avoid repeated parsing of URI, Host, Port etc) seems to be
mostly unused currently, I used that to pass the port.
