The first is unnecessary because after_expand() never returns NULL, and the 'rest' pointer has been

The second is unnecessary because parse_number(&ptr) cannot set ptr to NULL.
like x86-64, where sizeof(int) != sizeof (void *). This involves correctly
casting every function pointer from the global table to the correct
function type, which has the added benefit of allowing type-checking of
function arguments and return values.
