Should it be a user-error though?  Is there any scheme to set another keybinding
for `M-n` and `M-p` for things like completing-read?  Being able to use [up] and
[down] would be both convenient and intuitive (particularly people who use 
packages
like company-mode), but cannot see that completing-read could allow that.
