+  \item[(2)]
+    The alternate form causes a leading \code{'0x'} or \code{'0X'}
+    (depending on whether the \character{x} or \character{X} format
+    was used) to be inserted between left-hand padding and the

-(The \code{\%r} conversion was added in Python 2.0.)
-
 Since Python strings have an explicit length, \code{\%s} conversions
 do not assume that \code{'\e0'} is the end of the string.
