Yeah I am not sure if I like this comparison at the beginning of the
function:

        static int next_byte(const char **cp, const char **endp,
                             const struct diff_options *diffopt)
        {
                int retval;

                if (*cp > *endp)
                        return -1;

but it says endp _is_ part of valid input, contrary to my intuition.

And your change to the initialization of ae/be in moved_entry_cmp()
makes it consistent with it, I think.

But doesn't it mean ae computation in get_string_hash() also needs a
massaging?
