# 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.
