bug#16740: 24.2; Please allow C-p and C-n in minibuffer

Indeed.  I also noticed this inconsistency time ago.

I wonder why bash uses C-p/C-n instead of M-p/M-n for browsing the
command history.

Indeed Minibuffers have usually a single line of text, but not always.
  So, I think that the standard meaning of C-p/C-n (previous/next
line) is sometimes useful also in the minibuffer.

IOW, I'd rather change bash behavior to match the Emacs one, instead
of the other way around.
