Patch to expose prompt motion commands

[Ewan Mellor <sawfish ewanmellor org uk>]

I would like to add key bindings to the prompt-keymap.  However, to do that
usefully, the motion commands in prompt.jl must be exposed.  The following
patch achieves this; I would appreciate it if it could be applied to the main
codebase.

Cheers,

Ewan Mellor.
