end-of-file mode should respect read-only mode |

In the modeline the curious user sees a ":" and clicks it.
and sees [DOS], [Mac], etc.
Frightened, the user keeps clicking until he cycles back to its original
":" state, and breathes a sigh of relief.
But wait, it's time for lunch and time to close the editor program.
But now it's asking him about saving the file.
"I thought that -r--r--r-- file owned by the boss and which I viewed in
read-only mode, or even view-mode, was understood by everybody to be
something I didn't intend to meddle with." "Now it thinks I wanted to
modify it..."
Now with extra sweat dripping, he hits undo,
command-execute: Buffer is read-only: #<buffer
boss's_secret_employee_evaluations.txt>
"address@hidden it, half of the editor knows things are read-only, the other
half doesn't."
Sure, he can just answer "no" when asked to save the file. But why
embroil him this way in the first place. Readonly should be Readonly.
Now Curious Other User 2 also clicks the ":".
At the end when closing emacs she is asked if she wants to save the
file, to which she agrees. Which results in even more warnings and
eventual failure to save the file anyway...

I clarified this in a different way.
Thanks.
