I don't think this helps because where the prefix is an individual key
typed by the user, they are then forced to type the following character
in the sequence faster than KEYTIMEOUT. And if something like <Escape>a
is typed too fast from vi-mode, it would still be thrown out as a whole.
Taking the default emacs bindings, Ctrl-X is a prefix but we don't
want a timeout after Ctrl-X because it is the user typing followup
characters.

The current behaviour where the whole sequence is thrown out is
consistent with emacs. I think it makes sense for the typical emacs case
if you make a mistake with a manual sequence. We can't really
special-case escape because manual sequences with escape are also common
in emacs mode. Binding escape in vi command mode does, however, solve
it.
