This is the result of the rmcup entry in terminfo. For some reason the
behaviour of this is to save a copy of the screen as well as that
annoying clearing effect. This is why after using less compiled with
ncurses, when you quit less the file you were viewing disappears and you
see the command line screen you were in before you ran less. I hate this
so I delete the rmcup (and the corresponding te in termcap) from every
machine I work on. I have never found anyone who prefered the default
behavior. I've been doing this for several years and never found the
absence of rmcup (or te) to adversely affect any program I've used.

While I doubt we can get rid of rmcup on all the linux installations out
there, you could put a note in the menuconfig docs suggesting it if
people find it annoying.
