It seems to be orthogonal to "emacs --reverse-video", and has no effect when I try setting it manually in a running session, nor when I run "emacs --eval='(setq inverse-video t)' -Q -nw".

Anyway, it's in the C source code still. As I said, I can't discern any visible effects from setting it to t. By the way, the attached patch removes the variable. I'm not suggesting to install it as is, but perhaps it could be useful in figuring out what the inverse-video variable does and what to do about it.

I'd argue it's not an important feature. It seems like it's been broken for a long time without anyone complaining. We could remove it and refer any existing users to "emacs -rv" instead.

It doesn't follow that we should remove it. A bug is a bug. Better to keep this bug open. Someday, perhaps, Someone(TM) will be motivated and find a way to fix it. And if not, so what? What harm does it do to keep a report open for a recognized bug? When it comes to free software and its volunteers, no one's career is boosted by just reducing a bug count as an end in itself.

My point is that now -- 20 years after this stopped working -- we should step back a bit and look at whether this functionality (which must at this remove be seen to be a new feature) makes sense. And I don't think it does much. Setting a variable that makes the Emacs display go inverse?
