Subject: bug#16848: diff reports a diff on identical lines

On some pair of files, "diff" reports a diff on identical lines.
See the attached archive. At line 1272 of "diff -u out1 out2":

@@ -137681,90 +138934,186 @@
 26659

 462
-26946
+26946
+470

This chunk shouldn't contain:

-26946
+26946

There's the same problem without the "-u" option.
