When the fall-back of a case-statement is the last thing executed in a

while-loop _and_ all prior matches in the same case-statement either break
or continue, we can safely break the fall-back out of the case-statement.
This should improve readability and allow for longer-lines by reducing the
level of indentation by-one for the fall-back case.
