+- Deprecated the ``-insert`` and ``-remove`` command line options, and added
+  the ``-disable-remove`` and ``-disable-insert`` command line options as
+  replacements. The previous command line options were confusing because they
+  did not imply the default state of the option (which is inserts and removes
