A brute-force method is to repaint the screen before `less', and
to clear it afterwards, which can be done in `tcsh' with
alias less 'less -c \!* && clear'
However, this makes the screen contents prior to the `less' command
scroll off the top and become invisible. To avoid this, you can use
termcap(5) instead of the above alias:
setenv TERMCAP "xterm|xterm-color:tc=xterm-xfree86:"
setenv LESS "-cs"
setenv PAGER "less"

I used Debian for several years before moving to FreeBSD some years
ago. I don't remember particularly making an effort to deal with the
differences between them, so I can't help you there. FWIW, I found
