+# This function lists options with the no's in front removed for
+# improved comprehension, i.e. `norcs off' becomes `rcs on'.
+# The format is otherwise like that with `kshoptionprint' set,
+# i.e. you can see all options whether on or off.
+# It can take a list of option names or parts thereof to search for
+# via egrep.
