Agreed.  BTW my comments don't look dark red.

I very much like the current "\ " representation and the color
as well.

Agreed.

The only things we might want to change, from my point of view are:
- use the display-table rather than the new ad-hoc implementation.
- maybe revert to the original implementation where only the \ or the ^ was
  marked with a special color.  This one is just a personal preference.
