Disable command-line processing for Emacs 24.

There is no longer access to file-count/line/column after lexical
binding was introduced in Emacs 24 and enabled for startup.el, which
means the current implementation no longer works.

Probably it could be reimplemented using advice, but I personally
don't need the feature so I'm just leaving it disabled.
