Hi, I'm confused about the flag --print-long-lines.
Unless I'm misunderstanding something more fundamental about how you're supposed to use it,
it seems broken to me?

The manpage/help just says:
--print-long-lines Print matches on very long lines (Default: >2k characters)

But for me, long lines are printed by default,
and I can't find any way to turn that behavior off (or adjust it),
trying things like:

--print-long-lines false
--print-long-lines=false
--print-long-lines=no
--print-long-lines 100
--print-long-lines=100

(I made sure I didn't accidentally have ag wrapped in an alias that already included the flag or something ; my ag is indeed just plain /usr/bin/ag.)

Like, I just set up a test like this [(looks weird cuz fishshell)]:
$

for n in 2 20 200 2000 2200
	echo "$(string repeat -n (math "$n-1") "_")x" > file_$n.txt
end

(
such that
$

cat *

#=>

_x

)

and then both
$

ag x

and
$

ag x --print-long-lines

get exactly the same result

I actually passed that through pty and aha to try to keep the formatting/colors the same as you actually see when using it interactively
like:
$

pty ag x|aha -n -b

and then tried putting the output of that in <pre></pre> tags,
but of course that doesn't actually display the colors here...

I'm not sure how to get the colors to actually show up in a github comment,
if that's even possible(?),
but yeah,
the above block is actually underlyingly:

<pre>
<span style="font-weight:bold;color:lime;">file_2.txt</span>
<span style="font-weight:bold;color:yellow;">1</span>:_<span style="color:dimgray;background-color:yellow;">x</span>

Actually, now that I'm thinking about it,
maybe a feature request:
expand the "before/after/context" flags so they can also take number of characters before/after?
(Right now, they only take lines.)
