I decided to investigate it a bit more and made a small patch (attached) 
that will set the view mode if at least one file can't be written to. It 
can be suppressed with (also added) option -y (or --noview).

It's drawbacks however are that:

- flags must be changed to long long (or unsigned long) as there are
  all 31 bits used
- see NOTES in access(2) manpage

Feel free to test and use (and maybe even it will make it's way into the 
nano source tree?).

Kind regards.
