This will require a patch that includes test cases.  Preferably tests that can
be run with test-nohost ant target.  Must ensure that the escaping is done at
the "right" time.  

<cite href="http://www.ietf.org/rfc/rfc2396.txt">
2.4.2. When to Escape and Unescape

   A URI is always in an "escaped" form, since escaping or unescaping a
   completed URI might change its semantics.  Normally, the only time
   escape encodings can safely be made is when the URI is being created
   from its component parts; each component may have its own set of
   characters that are reserved, so only the mechanism responsible for
   generating or interpreting that component can determine whether or
   not escaping a character will change its semantics. Likewise, a URI
   must be separated into its components before the escaped characters
   within those components can be safely decoded.
