maybe disable scroll-left

[Dan Jacobson]

I found a keystroke that will leave users jumbled if accidentally hit:
C-x < runs the command scroll-left.
Hey man, where'd my text go? Undo, undo, undo... no relief.
Maybe it's hiding up at the top left corner somewhere? Hitting
beginning-of-buffer, backwards-char, beginning-of-line won't help.

Maybe "disable" scroll-left.
