It appears the issue may be with lessopen, and mostly works if you use 
-L to disable lessopen, but NUL chars are displayed around startup, so 
it's not as clean as:

	$ tail -n$COLUMNS -f ... | less +F

Maybe lessopen is disabled when input is from stdin?

I will test with the new release and see if it's better.
