Well, I've tried many of the suggestions given concerning this problems, but
the only thing that has changed is the description of the symptoms. Sorry
for the length of this post; you can scan for '------' to get the major
points.
--------
Recommendation 1 (Earnie Boyd): TERM=linux
    I already had this.
--------
Recommendation 2 (Jeff Sturm & Larry Hall): get latest cygwinb19.dll from
Sergey's site, and recompile ncurses and less myself, as both build easily
OOB.
    I already had latest dll, but ncurses didn't compile. I got 4.2 from the
canonical site, ftp://www.clark.net/pub/dickey/ncurses/...  Here's a quick
transcript snippet from configure / make:

** Configuration summary for NCURSES 4.2 980228:

--I don't speak 'sed' so I can't debug this...

and from make:

cd ncurses && make --unix INSTALL_PREFIX="" all
make[1]: *** No rule to make target `all'.  Stop.
make: *** [all] Error 2

Hey, wait a minute, I didn't say "make all" so stop whining about no "all"
target. I just said "make."  Oh well.
-------------
Recommendation 3 (Jan Tomasek): type 'cat file.name | less'
    this seems to work without bombing. But why? Other people don't have to
resort to this, so what's wrong with my setup? (and Jan's, too)
-------------
Recommendation 4 (Earnie Boyd): use a different precompiled port of
ncurses/less
    haven't tried this yet, but will do so soon.
-------------
Change in my assessment of behavior:
    The pattern I described with shortfiles and longfiles is bunk. More
experimentation showed there is no pattern that I can see. Sometimes less
bombs on short files, sometimes on long files, and sometimes it doesn't
bomb. As Jan reported, 'cat file.name | less' seems to work fine. If nothing
else works, I'll put a function in my .bashrc to do this as a workaround. If
anybody has anymore suggestions, I'll take 'em, and I'll let you know if
using a different port fixes the problem.

****Andy: does your port of ncurses / less / vim use terminfo, termcap, or a
terminfo with a fallback to termcap?
