Thanks, this is what I came up with for our test config and it passes 
all tests.  I've applied your patch.

     ScriptAlias /cgi/ @ServerRoot@/tmp/TestApp/script/testapp_cgi.pl/

     <IfModule mod_rewrite.c>
         <Location /rewrite>
             RewriteEngine on
             RewriteRule /rewrite/(.*) /cgi/$1
         </Location>
     </IfModule>
