Okay, let's rephrase that: instead of "visual effect", we can say it's 
for "visually hiding" parts of buffers. But not for changing their 
behaviors otherwise (e.g. changing syntax highlighting, etc).

In your other answer regarding the inside of a string, you seemed to 
have a different idea, though. Like, user narrowing would be able to 
affect all that stuff too.

This subthread goes back to my complaint that commands don't know how to 
*interpret* the current narrowing, thus which effects it should have.

To repeat:

   Either narrowing should be used to change lexical/grammatical/etc
   context, or it should not. Do we have any documentation that says one
   or the other way? That should affect how Lisp code deals with
   narrowing -- which interactive functions should widen, and so on.
