Eval-buffer works, init does not hl-line fix

[JOE Staursky <jnstaursky@gmail.com>]

I have written the following bit of emacs lisp that allows hl-line to
extend past end of buffer to the rest of the line.

Problem is, this only works if I use (eval-buffer) after start-up and not
when I have it saved inside my .emacs file.

However,

I doubt that could cause this sort of difficulty.

Basically I am trying to make the current highlight line act more like
contemporary editors.

what could be interfering in the init file but not while in buffer?

        (progn
            (setq hl-line-after-cursor (make-overlay
(line-end-position) (line-end-position)))
                (overlay-put hl-line-after-cursor 'after-string
                     (propertize (make-string (- (-

            (move-overlay hl-line-after-cursor (line-end-position)
