user has no business toggling overwrite-mode in read-only buffers

[Dan Jacobson]

In a new crackdown on excessive freedoms, prime minister Moi
recommends toggling overwrite-mode be outlawed in read-only buffers.

In an interview, he was quoted as saying "It just doesn't make sense.
Why should we allow kids to toggle it back and fourth if they can't
possibly use it?  They might get the wrong impression, that they can
write stuff!  Only later will they find out the real deal."
