I think you're right.  The even worse case from this point of view is if
you configure it as:

    [mergetool]
        mytool = 'f() {
            ... code to actually run the tool here ...
        }; f $BASE $REMOTE $LOCAL $MERGED'

which results in a false "unavailable" rather than just a useless check.
