Good point, I didn't think of that. Also, now that I think about it more, a
diagnostic ending in "after byte 0, line 0" is confusing in a command that
ordinarily uses origin-1 offsets.
I installed the attached further patch. With it, your example now outputs:
cmp: EOF on /dev/fd/63 after byte 5, line 2
This is more consistent with longstanding behavior:
$ cmp <(printf '1\nfoot') <(printf '1\nfoolery\n')
/dev/fd/63 /dev/fd/62 differ: byte 6, line 2
