+    The alternate form causes a leading zero (\character{0}) to be
+    inserted between left-hand padding and the formatting of the
+    number if the leading character of the result is not already a
+    zero.
+  \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
+    formatting of the number if the leading character of the result is
+    not already a zero.
+  \item[(3)]
+    The \code{\%r} conversion was added in Python 2.0.

 % XXX Examples?
 
-(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.
