I think that would be didactically bad after just mentioning that newlines in triple-quoted strings don't have to be escaped etc.
I think this would confuse the reader.
Better use print("""Usage...

It won't (at least in Python 3.1). I just tried it.

Sure. But I think that in an example that is essentially about whitespace produced by print, the actual whitespace in the output should match the actual behaviour of print. One why to get rid of this problem altogether is to add a 'print "done!"' or whatever at the end, or use a different separator from " ".
