So this should be doable in GNU ed as soon as we find a way to reset
the 'read_only' flag. Maybe by changing the name of the file with 'f'?

Since ed does not have a 'set' command, to emulate this interface it would
be necessary to add two commands (or one command with a special argument).

I have finally implemented it so that it warns only once; the first time that a command modifies a buffer loaded from a read-only file.
