   ""u2=<u1<u3 or: u3=<u2 and u1 is not in [u3,u2).  This works for
   unsigned and signed numbers (but not a mixture).  Another way to think
   about this word is to consider the numbers as a circle (wrapping
   around from @code{max-u} to 0 for unsigned, and from @code{max-n} to
   min-n for signed numbers); now consider the range from u2 towards
   increasing numbers up to and excluding u3 (giving an empty range if
   u2=u3; if u1 is in this range, @code{within} returns true.""
