RE: [Zope] Quoting

<dtml-var something cookie_quote> Quote all characters not allowed in a cookie

wouldn't <dtml-var something url_quote> do the job? That reminds me, it's silly that there's not <dtml-something url_unquote>, so I patched my zope to provide it. I was wondering if there's a mechanism for getting this kind of simple tweak into the source tree? seb
