  Log:
  A gross hack to stop the pretty-printer going into an infinite loop.
  What happens is that 'indent' is given a negative number, and that
  made it loop.  This patch checks for the negative case, so at least
  it doesn't loop -- but I don't understand why the indent ever goes negative,
  so there's still something wrong here.
