Re: patch to include EasyPG to Emacs

[Richard Stallman]

    Even if you somehow manage to prevent the system from swapping out the
    memory used by Emacs to directly represent the buffer, other elisp code
    that interacts with the buffer may end up copying portions of the buffer
    contents to other locations in memory, or copied to other programs,
    e.g. if a spell checking mode is used.

It should be straightforward to prevent those modes from being enabled
in a buffer where you read a decrypted message.  That buffer should
normally be read-only, right?

Normally we should not enable these modes in read-only buffers, right?
Is that not implemented now?
