Downloading & trying versions of it locally reveals that it's as of

it's covered by this item in the changelog:

    Don't output terminal init sequence if using -F and file fits on one
    screen[1]

Side note: that's sad, because we already use X in the default exactly
for that reason.

So apparently "less" was broken for us to fix something that we
already had long solved. The code basically tried to do "automatic X
when F is set".

And all that line_count stuff (which is what breaks) is pointless when
-X is already given.

That does give a possible fix: just stop doing the line_count thing if
no_init is set.

So "-F" would continue to be broken, but "-FX" would work.

Something like the attached patch, perhaps?
