Are you overflowing the dst/src ports for the 16 bit case by any chance?
 With the 8bit port fix patch, we're actually using 24 bits to store
these values.  There might need to be a comment in the history API about
this.

Are 8 bit ports even used in practice?  If not, then might be that
shifting 8-bit values by 16 is better...

Other than that, I'm happy with this one.
