+You can specify the 'label_suffix' argument to a Form class to modify the
+punctuation symbol used at the end of a label.  By default, the colon (:) is
+used, and is only appended to the label if the label doesn't already end with a
+punctuation symbol: ., !, ? or :.  If you specify a different suffix, it will
+be appended regardless of the last character of the label.
