Vim may not properly work with ":set cpo+=W"

[Jason Franklin]

Perhaps I'm not understanding how this option works.

When I create a file on my desktop with write permission and open
it with "vim -R file.txt", I can run ":set cpo+=W" and then still
write the file with :w! or by confirming a prompt (with :set confirm).

Is this the intended behavior?

I would like to stop myself from *ever* overwriting a file that has
the 'readonly' option set (unless I manually disable 'ro').

Thanks,
Jason Franklin

What matters is if the file is read-only, not whether 'readonly' is set.

There is the 'write' option, but it's global. Perhaps we should make it
global-local?
