Error in the signup script due to double escapes

[nico]

Double escape characters "\" caused the signup-list1.cgi script to fail.

I had to change this:
   # sign up
   $sys_cmd = $http_program . "\\?cgi=1\\&list=$list\\&email=$em";
   if($fn ne '') { $sys_cmd = $sys_cmd . "\\&fname=$fn"; }
   if($ln ne '') {
    $ln = encode($ln);
    $sys_cmd = $sys_cmd . "\\&lname=$ln";
   }

To this before it worked:
   # sign up
   $sys_cmd = $http_program . "\?cgi=1\&list=$list\&email=$em";
   if($fn ne '') { $sys_cmd = $sys_cmd . "\&fname=$fn"; }
   if($ln ne '') {
    $ln = encode($ln);
    $sys_cmd = $sys_cmd . "\&lname=$ln";
   }

I guess this depends on your operating system and Perl settings.  The reason I use two slashes is so that Perl continues to pass an extra slash to the shell (wget) for certain characters, which is (only most often, apparently) required.
