Hello,
the page up / page down bindings that I've added earlier were only for
insert mode. The patch binds them also in vicmd.

Other basic editor keys are Home, End, moving cursor to beginning or
end of line. I've added bindings for them, both to emacs/insert and to
vicmd. $terminfo was wrong about my khome, kend codes, so I've also
added a fallback bindings. I think such fallbacks is what normal
projects are doing – accumulate real-world situations.
