[issue2771] test issue

"This is a very long line.  I am wondering how it will be wrapped. What
will happen to this exceedingly long line? Will it be wrapped? Will it?
Really? What will happen?

Here's an example:

  def fact(n):
    if n > 1:
      return n * fact(n-1)
    else:
      assert n in (0, 1)
      return 1

What do you think of that?"
