mod_rewrite while proxying request appends extra r->args

           Summary: mod_rewrite while proxying request appends extra r->args
           Product: Apache httpd-1.3
           Version: HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_rewrite
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: PAF@design.ru


situation: 
  http://first [mod_rewrite+mod_proxy]
  http://second [real server]

first:
.htaccess in / contains
RewriteEngine On
RewriteRule ^(.*)$ http://second/$1 [P]

first receives request:
http://first/test/?query

second receives this:
http://second/test/%3Fquery?query

which is wrong.

currently am fixing that by deleting may-be-buggy fragment of code in 
mod_rewrite in two places:
/* make sure the QUERY_STRING
...
get incorporated
*/
when query strings get's appended to filename:
                r->filename = ap_pstrcat(r->pool, r->filename,
                                         "?", r->args, NULL);

BUT it nobody ever removes r->args, and later on mod_proxy extracts r->args, 
while r->filename actually becomes urlencoded.
