Cleanup: break before the default case in switch statements

While missing the break before a default that only breaks isn't
an error, it means adding new cases needs to remember to add the
break for an existing case, changing the default case will also
result in an unintended fall-through.

Also avoid `default:;` and add an explicit break.
