The way the "colors" function/array have dealt with similar issues is
to declare e.g color[grey]=${color[black]} ... however, the difference
between negative image and italic may be too drastic to alias that to
standout.

I believe the use of "standout" there comes from the xterm
documentation (circa the time the colors function was contributed, it
may have since been updated).

Could use standout_enter/exit (or enter/end).
