If I were to exit with a 1 upon failure, I would also dispense with the
printing of No match. When I wrote this, I was using hte input and
output as given to me on the spec sheet (the currently working program).
If I had my druthers, I would do the silent failure with an exit code of
non-zero (probably 1, unless I had a good reason otherwise).
