RE: highlight current line when Emacs is idle

    This suggestion (for after the release) is a follow-on to my
    suggestion to change the cursor to a box when Emacs is idle
    in order to more easily spot it.

    Suggestion: Optionally turn on `global-hl-line-mode' and highlight the
    current line only when Emacs is idle.

A follow-on to that follow-on: Perhaps optionally highlight the current
column as well.

I use code in Rick Bielawski's library column-marker.el to do this.
Highlighting (faintly) both the current line and column provides a
cross-hairs effect that makes the cursor very easy to locate.

One use of this might be for better accessibility for people who are
visually impaired. I use an idle timer of several seconds for this myself,
but setting the timer interval to zero gives a pair of cross hairs as wide
and high as the buffer that track the cursor continually.
