Please don't skip the following four lines:
len = pend + 1 - p; \
PARSE_MULTIBYTE_SEQ (p, len, bytes); \
if (bytes == len) \
pos_byte -= len - 1; \
which handles the above case. When we at last reach a
char-head, PARSE_MULTIBYTE_SEQ checks how long the byte
sequence should be. We update pos_byte only if the length
is the same as what we decreased.
