Patch for less v97

[Chad R. Larson]

When less (version 97) is running with the "-c" option, it paints new
data from the top down, and clears each screen line immediately before
writing a new one.  This gets confused when outputting lines wider than
the physical screen on terminals that do auto-margin line wrapping.  The
continuation line can have left-over data from the previous screen
sticking out to the right margin.  This patch fixes the problem.
NOTE: The old code made outputting a newline character at the end of an
output line conditional on the termcap entries for auto-margins and the
VT100 glitch check.  I can't see the reason why and dropped it in my
patch.  If I'm braindamaged and that was necessary, 'scuse me.
