How to change the defaults for file highlighting?

[Theodore Kilgore <kilgota banach math auburn edu>]

Until very recently in the history of MC, file highlighting with 
Keypad-Plus highlighted only files. Now this behavior has been changed. A 
dialog box comes up which has a couple of useful features and one feature 
which from my perspective is both useless and irritating, especially 
since I became used to the opposite behavior for the previous ten years 
of constant desktop use of MC. This one

 [ ] Files only

Since it has been decided that a dialog for this "feature" has to be 
there, is there any configuration option by which one can change the 
default choice to be

 [x] Files only

instead of

 [ ] Files only

?

If there is such an option, I have not succeeded in finding it.
