-\item[(1)] Values of \var{n} less than \code{0} are treated as
+\item[(1)] When \var{s} is a string or Unicode string object the
+\code{in} and \code{not in} operations act like a substring test. In
+Python versions before 2.3, \var{x} had to be a string of length 1.
+In Python 2.3 and beyond, \var{x} may be a string of any length.

+\item[(2)] Values of \var{n} less than \code{0} are treated as
\code{0} (which yields an empty sequence of the same type as
\var{s}). Note also that the copies are shallow; nested structures
are not copied. This often haunts new Python programmers; consider:
