* Lisp Changes in Emacs 21.3
** Already true in Emacs 21.1, but not emphasized clearly enough:
Multibyte buffers can now faithfully record all 256 character codes
from 0 to 255. As a result, most of the past reasons to use unibyte
buffers no longer exist. We only know of three reasons to use them
now:
1. If you prefer to use unibyte text all of the time.
2. For reading files into temporary buffers, when you want to avoid
the time it takes to convert the format.
3. For binary files where format conversion would be pointless and
wasteful.
** If text has a `keymap' property, that keymap takes precedence
over minor mode keymaps.
