Narrowing is useful as a poor man's mmm-mode, among other things, and 
programatically, it's useful for parsing delimited constructs (where we 
can just narrow to the region of interest). Narrowing hasn't been a 
purely visual hint, and plenty of lisp-level functions treat the edges 
of the accessible portion of the buffer as real buffer ends. Since this 
abstraction almost completely works today, we should try to fill any 
remaining gaps.
