ibuffer appropriating arrows

[Dan Jacobson]

<right> runs the command ibuffer-forward-filter-group

Which is very disturbing, as I've always felt those arrow keys belong
to me and I don't recall them having been hijacked before. Next thing
you know they'll be usurping trusty C-f.

Anyways, touch a right or left arrow and wham, you're sent to the
bottom or top of the buffer with no way to get back or remember where
you were. As far as the filter stuff, I've never tried it. I'm sure it
must be wonderful...
OK, I already have
(setq ibuffer-movement-cycle nil); fixes up and down
But I suppose I must mess in the keymaps to fix right and left...
