Title:
  sub url from perl cgi library fails on special characters

Status in perl package in Ubuntu:
  New

Bug description:
  Binary package hint: perl

  hardy: ii  perl                                        5.8.8-12ubuntu0.4                     Larry Wall's Practical Extraction and Report
  lucid:  ii  perl                            5.10.1-8ubuntu2.1                 Larry Wall's Practical Extraction and Report

  
  Between Hardy and Lucid, CGI.pm has a change that breaks "sub url" when both the request_uri and the target contains special characters:

  root at cricket:/usr/share/perl/5.10.1# diff CGI.pm.orig CGI.pm
  2740c2740
  <     my $request_uri =  unescape($self->request_uri) || '';
  ---
  >     my $request_uri =  $self->request_uri || '';

  If you pass in a target with a special character (in my case a +) and
  your $request_uri includes that character the outputed url includes an
  http escaped version of the $request_uri followed by the target url:

  
  #run from /home/one+two
  $cgi = new CGI;
  $cgi->path_info('/home/one+two/link');
  print $cgi->url(-relative=>1,
                       -query=>1,
                       -path_info=>1);
  #output: /home/one%20two/home/one+two/link

  
  I'm not sure why this change was made, so I don't know what other side effect it will have, but it breaks all URLs that contain special characters, so it should be removed.
