Please don't usurp M-<LEFT> and M-<RIGHT>, as they are needed on TTY frames
where C-<LEFT> and C-<RIGHT> are not available.

I don't really understand the difference between minibuffer-previous-* and
minibuffer-previous-line-* commands (the available documentation is minimal
and doesn't explain this difference), so it's hard to suggest an
alternative.  But one immediate alternative is to use <LEFT> and <RIGHT> for
the minibuffer-previous-* family, like previous-completion does.
