 Environment variable ``CDIFF_OPTIONS`` may be used to specify default options
 that will be placed at the beginning of the argument list, for example:
 
 .. code-block:: bash
 
-    export CDIFF_OPTIONS='-s -w0'
-    cdiff foo                   # equivalent to "cdiff -s -w0 foo"
+    export CDIFF_OPTIONS='-s -w0 --wrap'
+    cdiff foo                   # equivalent to "cdiff -s -w0 --wrap foo"
 
 If you feel more comfortable with a command such as ``git cdiff`` to trigger
 the cdiff command, you may symlink the executable to one named ``git-cdiff``
