PATCH: Add SHORT_KEYBIND_DISCARD option



Not sure how popular this option would be, but I'm fine with keeping
it local too. Basically when we encounter an undefined key, instead
of discarding the entire common prefix, we discard only one byte and
try again. In most particular, it means if you happen to press escape
or ctrl-x before pasting, we still properly detect the bracketed-paste
starting code.
