I've checked it.  All the other places are safe.

Here's a comment of the usage of str_as_multibyte in ccl.c
(line 2152) and coding.c (line 4513).  They both try to make
the byte sequence produced by ccl_dirver sane as multibyte.
For that, we don't have to check the buffer overrun because
ccl_driver never produces the byte sequence longer than:
    DST_BYTES - _NUMBER_OF_EIGHT_BIT_CONTROL_CHARS_PRODUCED_
