 The sample wrapper scripts diffwrap.sh and diffwrap.bat each pull the
 diff-able files from their sixth and seventh arguments.  But if you use
 'svn diff --diff-cmd -x ARG1 ARG2', the fact that -x causes the formerly
 hardcoded "-u" argument to be replaced with "ARG1" "ARG2" means the diff-
 able files are now in the seventh and eighth argument slots.

 Clearly, to be fully robust, these wrapper scripts need to looking at the
 last two arguments regardless of how many arguments appear.
