 @defopt ignored-local-variable-values
-If there are some local variables that you always want to always
-ignore, this variable can be used.  It uses the same syntax as
-@code{safe-local-variable-values}, but the variable/value pairs here
-will always be ignored when handling local variables.  As with that
-variable, when Emacs queries the user about whether to obey a
-file-local variable, the user can choose to ignore them permanently,
-and that will alter this variable and save it to the user's custom file.
+If there are some values of particular local variables that you always
+want to ignore completely, you can this variable.  Its value has the
+same form as @code{safe-local-variable-values}; a file-local variable
+setting to the value that appears in the list will always be ignored
+when processing the local variables specified by the file.  As with
+that variable, when Emacs queries the user about whether to obey a
+file-local variable, you can choose to ignore their particular values
+permanently, and that will alter this variable and save it to the
+user's custom file.  Variable-value pairs that appear in this variable
+take precedence over the same pairs in @code{safe-local-variable-values}.
