code review: switch case breaks.

* arith.c (c_unum): Add fallthrough comment.
(minus): Add missing break after case that handles char minus
heap object.. This luckily isn't a bug because type(anum)
isn't RNG, and so when it falls through, the next case also
falls through.

* lib.c (car): Add missing fallthrough comment.
