It can't do it directly but it can invoke a script and the script can do
anything. Parse the label to get the working copy path, run a propget
to get svn:mime-type and then invoke GNU diff or special diff as
appropriate. Or on Linux it could run 'file --mimetype' on the given
file and use that instead of svn:mime-type.
