+- difflib's SequenceMatcher class now does a dynamic analysis of
+  which elements are so frequent as to constitute noise.  For
+  comparing files as sequences of lines, this generally works better
+  than the IS_LINE_JUNK function, and function ndiff's linejunk
+  argument defaults to None now as a result.  A happy benefit is
+  that SequenceMatcher may run much faster now when applied
+  to large files with many duplicate lines (for example, C program
+  text with lots of repeated "}" and "return NULL;" lines).
