Subject: [PATCH] Add C-z C-v for literal next

A little annoying to make it a "chord" like this, but C-v is already
used for scrolling, following Emacs-style key bindings (in order
to have a way to scroll without using "special" keys like the arrows
and page up/down), and C-z is at least already in the business of
inserting control characters. This makes it possible to manually
enter some things that are otherwise only possible with /exec printf.
