Refactor the first clauses so that a violation of
MISRA C Rule 16.2 is resolved (a switch label should be immediately
enclosed in the compound statement of the switch).
Note that the switch clause ending with the pseudo
keyword "fallthrough" is an allowed exception to Rule 16.3.

Convert fallthrough comments in other clauses to the pseudo-keyword
while at it.

No functional change.
