Correct.  For whatever reason MS decided to support a limited form of
chmod where you could make a file read-only, which probably just calls
SetFileAttributes() behind the scenes.  I'm not sure why they did this,
other than to try to be more *nix compatible.  In the end I think it
just confuses people.

No, you're not wrong.
