multiple slashes in DocumentRoot are not handled properly by mod_rewrite in per-dir mode

           Summary: multiple slashes in DocumentRoot are not handled
                    properly by mod_rewrite in per-dir mode
           Product: Apache httpd-1.3
           Version: 1.3.26
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: mod_rewrite
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: novodim@xiag.ch


When using rules from .htaccess (switching to per-dir mode) and as DocumentRoot 
something like:
DocumentRoot /var/www//rewrite

The URL given for actual processing is not what was expected. 

Example (requesting the / of the site):

---->> httpd.conf
...
DocumentRoot /var/www//rewrite
...
---->> end of httpd.conf 


---->> .htaccess
RewriteEngine on
RewriteRule ^/$ /url_handle.php [L]
---->> end of .htaccess

---->> rewrite_log
...
[per-dir /var/www/rewrite/] add path-info postfix: /var/www//rewrite -
> /var/www//rewrite/
[per-dir /var/www/rewrite/] applying pattern '^/$' to uri '/var/www//rewrite/'
[per-dir /var/www/rewrite/] pass through /var/www//rewrite
...
---->> End of rewrite_log

as we see in the example above the pattern was applied to the 
string "/var/www//rewrite/", instead of "/" as we could think, because strncmp 
function used in mod_rewrite considered different the two 
strings /var/www//rewrite and /var/www/rewrite. Actually strncmp was right and 
probably it's a question of bad style - having extra slashes in DocumentRoot 
path, but there is no caution of not doing so in documentation.
