 @cindex risky variable
   Some variables, such as @code{load-path}, are considered
 particularly @dfn{risky}: there is seldom any reason to specify them
-as local variables, and changing them can be dangerous.  Even if you
-enter @kbd{!} at the confirmation prompt, Emacs will not record any
-values as safe for these variables.  If you really want to record safe
-values for these variables, do it directly by customizing
+as local variables, and changing them can be dangerous.  If a file
+contains only risky local variables, Emacs neither offers nor accepts
+@kbd{!} as input at the confirmation prompt.  If some of the local
+variables in a file are risky, and some are only potentially unsafe, you
+can enter @kbd{!} at the prompt.  It applies all the variables, but only
+marks the non-risky ones as safe for the future.  If you really want to
+record safe values for risky variables, do it directly by customizing
 @samp{safe-local-variable-values} (@pxref{Easy Customization}).
