OK.  I was hoping that "imitate surrounding code" was sufficient,
but it seems many parts of the codebase have deteriorated enough to
make that rule no longer easy to follow.

That is your itch and the idea and the bulk of the changes remains
to be yours in any case, methinks.

By the way, there is no reason for my patch to be unshifting the "#unmatch"
token into the array and spewing the array out, if the readers are always
going to stop upon seeing "#unmatch" without touching any submodule
that is named correctly on the command line.  In other words, the
following should suffice:

        while (<>) {
                ... accumulate in @out ...
        if ($unmatched) {
                print "#unmatched\n";
        } else {
                print for (@out);
