                  while less(1) when running as less does.

                  The less(1) behavior can be annoying to some people 
(sometimes even
                  myself when using less to show contents of a file and ^Z to 
                  them), and unfortunately quite a few of them also happen to 
be the
                  more vocal ones when it comes to a change.

            I find that behaviour infuriating

            I page down to a place to get some text on the screen to use as  a 
reference, then exit to run a command with that information, and *bam* the info 
I wanted to
            use has gone away.

      It doesn't do that on csh.  Or maybe I figured out how to prevent it long 
ago and forgot, but all I use is this:

      setenv  PAGER   "less -RS"

You probably did what I used to do. Modify the termcaps/terminfo to eliminate 
this behavior. See Exorcising the Evil Alternate Screen.

In the past, FreeBSD disabled this by default. It was changed several years 
ago, but you can change it back as per the aboved referenced article.

I'm pretty sure I have not done that, it would show up in mergemaster. As far as I can remember, less(1) has never done that clear-the-screen thing on FreeBSD, which is why it is so jarring on Linux.
