Have you looked at the --trust-exit-code option to git-difftool? It would be nice if there was a way to differentiate between complete failure and just the diff tool exiting with a non-zero return status because the files differ, but I'm not sure whether we can do that reliably. POSIX uses 127 and 126 as errors that mean the command didn't run [1] so it may be sensible to to treat those as special values.
