You're perfectly right! Back then I had some issues with the "clean" solution and no idea how to do it better. It just worked, so I kept it like this :)
You made me feel a bit challenged, though, so I've decided I'll try to fix the issue.
Basically, the ideal solution would look like this:
For some reason, it doesn't work in the case when there is nothing to clean - line count is always equal or greater to one. I cannot remember it, but I suppose that was the exact issue five years ago when I was writing the script.
But now I'm smarter (or just know Bash a bit more :) ) and I know how to do it right! echo adds a new line to the end of the printed string, even when it's empty. Unless -n switch is specified! So the code below works perfectly in all cases.
