I just tried to reuse this program that was posted several months ago.
I am using a text flie that is about 200 lines long and have named it
win.txt. The file it creates when I run the program is win_new.txt
but it's empty.
Although it creates a file called "win_new.txt", it then renames it to
"win.txt", so "win_new.txt" shouldn't exist.
Of course, if there's already a file called "win_old.txt", then the
first rename will raise an exception, and you'll have "win_new.txt" and
the original "win.txt".
