Fair enough, looks reasonable.

Except your case-statement sucks. Having a "case 'c':" that basically
then immediately has an "if (it was not 'c')" is just disturbing. Just
move the code that is common to all the cases outside the case
statement entirely, and make the 'c' case not do anything at all, and
remove that crazy extraneous if-statement.
