Remove ^E and ^Y

^E and ^Y are characters reserved by POSIX shell in emacs
editing mode for "control of line" and "yank". St is generating
^E and ^Y as a hack because vi and less uses them for scroll
backward/forward. being the only terminal emulator where
mouse wheel can be used with them. A new patch was sent to
st to do the same trick for terminal scroll, and making st
returns shift+prev/next for shift+wheel.
