I think your patch is correct. I've quoted it below so others can see
it. A couple of comments:

   1. A log message always helps :-). See
      http://subversion.tigris.org/hacking.html#log-messages

   2. You attached it with MIME-type "application/octet-stream", which
      means that mailreaders can't display it inline. If you use
      "text/plain" instead, that makes things a bit easier. See
      http://subversion.tigris.org/hacking.html#patches

The guideline for URI encoding and decoding is just to follow the doc
strings of whatever functions the data will be passed to. If the
function says it needs URI-encoded data, then make sure it receives
that. If it does not, then usually it takes un-encoded data.
