/* Safely get two bytes from the source text pointed by SRC which ends
at SRC_END, and set C1 and C2 to those bytes. If there are not
enough bytes in the source for C1, it jumps to `no_more_source'.
If there are not enough bytes in the source for C2, set C2 to -1.
If multibytep is nonzero and a multibyte character is found at SRC,
set C1 and/or C2 to the negative value of the character code. The
caller should declare and set these variables appropriately in
advance:
at SRC_END, and set C1 and C2 to those bytes while skipping the

It is intended that this macro is used in detect_coding_utf_16. */
