Your response here tells me that I was wrong in thinking that you were
deliberately ignoring my messages.  Please understand my assumption
was based upon a lack of response to three messages.  (2 email, 1
notes)

Perhaps I can be of assistance.  I am willing (time permitting) to try
out less on a pre-release basis and report back to you any problems I
find.

This is the first time I heard of this.  I did not save this version
for myself (since I prefer to use a version with emacs bindings hacked
in and I don't currently have time to hack them in) but passed it on
to a friend whose computer is unreachable by me.  So I cannot check
this:  did you or can you mention this in some of the documentation?

Of course I will need to check that this does not break other software...

Clearly I cannot make such a guarantee.  I have access to only a few
types of non-HP terminals.  The more I learn about the different
escape sequence languages for all the different types of terminals in
the industry, the more amazed I am that termcap and curses work as
well as they do.  In fact, even with this incompatibility of less with
HP terminals, it still works most of the time.

Thank you.  I could ask for no more.
