What's the k in line 28 good for?

It should be just
1
for line in io.lines(file, 'r') do
without the ,k

Or is there any special meaning behind the k? It looks just wrong if you ask me.

You added it? Why? It makes no sense
Or maybe LuaJIT just doesn't provide io.lines. I don't know

Put this into a file in /sys/autorun/
It should output text to console and it worked for me. There's nothing significant I changed.

function lines_from(file)
	local lines = {}
	local f = io.open(file, "r")
	for line in f:lines() do
		print("Line: "..line)
		table.insert(lines, explode("\t", line))
	end
	f:close()
	return lines
end
What I actually think that doesn't make sense is this:
1
io.lines(file, 'r')
Because io.lines has only one argument.

Edit: or user VADemon which seems more reliable.
