Yeah, that was the fatal flaw in my little post there. That is one
very cool ANSI code though.  I've used the color codes, but did not
know about that one :)

I just tried it out, and that is the correct code :)

clear = "\e[K"
print "a very long line of text that is longer than the next line"
sleep 1
print "\rshort line of text#{clear}"
sleep 1
print "\n"

By the way "\e" == "\033"
