Some methods (GET, HEAD, and PUT) perform path encoding, while all other methods
do not.  The constrcutor for the encoding methods looks like:

   super(URLUtil.URLEncode(path, "UTF-8"));

while all other methods look like:

   super (path);

All methods should be either encoded or decoded in order to ensure that double
encoding doesn't take place.  This problem will only be visible when attempting
to operate on resource which require encoding (i.e. there is a space in the
name).  Given that list() returns the child names unencoded, I would think it
would make the most sense to always expect unencoded paths.
