Line breaks being removed?

Hi, i Created my own program to make farming, all was working perfect, but when i saved it, and runned the program, the turtle stucked in a loop just excavating the block below, (with saving i mean to put in the Computercraft -> lua -> programs folder)
the first code (that wasn´t saved) is this:

turtle.up()
turtle.forward()
while turtle.detectDown() do
turtle.digDown()
turtle.forward()
end
while not turtle.detectDown() do
turtle.turnRight()
turtle.forward()
turtle.turnRight()
turtle.forward()
end
while turtle.detectDown() do
turtle.digDown()
turtle.forward()
end
while not turtle.detectDown() do
turtle.turnLeft()
turtle.forward()
turtle.turnLeft()
turtle.forward()
end
while turtle.detectDown() do
turtle.digDown()
turtle.forward()
end
turtle.turnRight()
turtle.down()
turtle.forward()
turtle.turnRight()
while not turtle.detect() do
turtle.forward()
end
turtle.drop(10)
turtle.drop(10)

but after saving the code it was looking like this:

turtle.up()
turtle.forward()while turtle.detectDown() doturtle.digDown()turtle.forward()

end
while not turtle.detectDown() do
turtle.turnRight()
turtle.forward()
turtle.turnRight()

turtle.forward()
endwhile turtle.detectDown() do
turtle.digDown()turtle.forward()
endwhile not turtle.detectDown() do
turtle.turnLeft()turtle.forward()turtle.turnLeft()
turtle.forward()endwhileturtle.detectDown() doturtle.digDown()
turtle.forward()
end

turtle.turnRight()
turtle.down()turtle.forward()turtle.turnRight()
while not turtle.detect() do
turtle.forward()
endturtle.drop(10)turtle.drop(10)

(i used the notepad aplication to see the code)
Please help me! :(/>

Split into new topic. A title was provided for you.

Sublime, notepad++, try those, they work a ton better than notepad.
