I think decode_coding_gap might segfault because you use insert_1_both
to put the text into the buffer.  By contrast, decode_coding_gap
assumes you've copied the bytes into the gap, like we do in
Finsert_file_contents.

I don't think we can bypass decoding in this case; the reason why you
think it isn't needed is because you only tried that with valid UTF-8
encoded text.  We never rely on that elsewhere, AFAIK.
