I see C's if as an exclusive two-case switch. If doesn't need break
because fallthrough in an if would be useless -- any code common to the
then and else clauses can be factored out of the if, since there are no
other cases. "If", as a _special_ _case_ of switch, assumes a break;
would C be better if "then" required a break to prevent fallthrough to
the else? That would be a consistent way to make them similar.
