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.
