Everything to the right of the '?' is a query, not part of the url.

There is nothing about using '+' for the white spaces instead of '%20' that coincides with current general usage.  So far all of the references have been stale and obscure.  It appears to me that '+' is being proposed only because it can possibly be used, not because it's the best way.

In RFC 2396 (url="http://www.ietf.org/rfc/rfc2396.txt") the escapement for the white space in a url is '%20'.  This was a reference for the XLink Working Group's W3C Proposed Recommendation 20 December 2000 (url="http://www.w3.org/TR/2000/PR-xlink-20001220/") that Paul was a member of.  In 2.4.3. Excluded US-ASCII Characters
, 2396 states 'Whitespace is also used to delimit URI in many
   contexts.

   space       = <US-ASCII coded character 20 hexadecimal>'

In the bibliographic citations for RFC 2396, RFC1866 is cited.  So whatever points may have been contained in 1866 have been considered, and it can be considered to be superseded by 2396.

I suggest that it is inappropriate for us to change it at this point.

A W3C Recommendation isn't a standard either.

In fact, every time you fill out a form in a browser, all the spaces you type
in are sent to the server as plus signs.  In the case of a POST,
this is done stand-alone, but if the form is of type GET, then the plus signs
are directly in the search part of the URL, right after the "?" character.

Dereference this URL in various browsers and see what you get:

http://www.google.com/search?q=XML+parsers
