Subject: [PATCH] Allow windmove keys to be bound without prefix or modifiers

[Message part 1 (text/plain, inline)]

Hi,

I'm probably not the only one who tends to use C-{f,b,n,p} over the
arrow keys, but also sometimes gets annoyed by navigating windows. I
recently realised that the reason I didn't use windmove as much as I
would want to, was that I coudln't find a satisfying modifier-key. My
idea was then to try windmove without any modifier, and I quite like
it. The only "annoying" thing is that I have to bind all keys
manually, instead of using a function like
`windmove-default-keybindings', because `nil' is interpreted as a
default binding.

This patch adds a pseudo-modifier (`none') to allow bindings the
windmove functions without any real modifier or prefix key, depending on
the function.

Another question I'd like to ask before trying it out: Would there be
any interest in adding user options for the "default" modifiers that
windmove should use? If yes, one could add a :set function that
automatically calls the apropriate bindings function, when it's value
is non-nil. I have a very customize-centric configuration, where something
this would fit in very well.
