I just tried this, when you open a read-only file as a normal user it gives
you a warning.

edward@x230:~$ touch test
edward@x230:~$ chmod 400 test
edward@x230:~$ nano test

Nano says:

 [ Read 0 line ( Warning: No write permission) ]

It won't let me save the file with the same name, I get this error:

 [ Error writing test: Permission denied ]

When running as root the warning and error disappear, there is no indication
that the file is read-only.
