Detecting if a terminal can do reverse video

[Mike Aubury]

Or more to the point - that it can't!

Is there any easy way to detect this ? 

Background..
I need to add some emphasis to the "current" menu option which I'm doing by 
making it in REVERSE video, but some terminals can't do reverse, so I'm 
supposed to put "[" and "]" around the option. I've got the code working with 
an environment variable, but it'd be nice if I could just detect it...

TIA..
