So the line below the last line of the file isn't actually considered an 
empty line, even though you can move the cursor to it in a text editor?

If you have a file that has one line and it ends with a newline, at 
least in my text editor the cursor then moves down to the next line, but 
is this just a detail of the way the editor itself works, and nothing to 
do with the file? (i.e., there is really only one line in the file, not 
two?)
