Editing in Insert State
-----------------------
Minibuffer can be edited similarly to Insert state, and you can
switch between Insert/Replace/Vi states at will. Some users prefer
plain Emacs feel in the Minibuffer. To this end, set
VIPER-VI-STYLE-IN-MINIBUFFER to `nil'.
`C-v'
Deprive the next char of its special meaning (quoting).
`C-h'
One char back.
`C-w'
One word back.
`C-u'
Back to the begin of the change on the current line.
