# note: An alpha plane back-reference starting one byte off a word boundary.
# expect: ok
# unique: copy8b_unaligned copy8b_tail
# exercises: CopySmallPattern8b()'s two ends. It writes whole words, so a
#   copy that does not start on a word boundary is walked byte by byte
#   first, rotating the pattern along the way; a length that is not a
#   multiple of four leaves a tail behind at the other end. 33 bytes in and
#   13 long, so both run.
