I pulled it off the net, so it must be 1.1.0.

Hmm.  I am using Win2K if that makes any difference.  It seems that the display
is always messed up for me when the file being viewed has lines that wrap
(i.e., longer than $COLUMNS, which is 80 for me).  I don't use a horizontal
scrollbar.

If I pipe a file with the majority of its lines longer than 80 characters I get
an extra newline everywhere a lines wraps, and after `G' `g', I can no longer
view the top of the buffer.  Same behavior when running under bash (as opposed
to zsh, my preferred shell).

The B20.1 `less' doesn't exhibit this behavior.  In fact, I've just discovered
that display problems with my B20.1 less only show up when I provide the -r
option.  I guess I'll revert to the B20.1 version for now...

Please Cc me on any replies as I'm not a member of the list.
