I don't strongly object to this, but I wonder how useful it will
really be in practice. It strikes me as the sort of advanced psql
hackery that only a few people will use, and only some of those will
gain any benefit. Empty columns don't really take up that much screen
width, and even one value in any given column will require its
inclusion anyway. I can also see myself turning it on and then going
- oh, wait, is that column not there, or did it just disappear because
I'm in concise mode?
Not saying we shouldn't do it, just some food for thought.
