Wording in safe local variables message

[Ralf Angeli]

It seems that many people are having a hard time understanding how to
mark file-local variables permanently as safe.  Maybe improving the
respective instructions in the pop-up message could help.  Currently
it says

!  -- to apply the local variables list, and mark these values (*) as
      safe (in the future, they can be set automatically.)

How about the following?

!  -- to apply the local variables list, and permanently mark these
      values (*) as safe (in the future, they will be set automatically.)
