  Log:
  Fixed some comments added in rev.1.5.
  
  The log message for 1.5 said that some small (one or two ulp) inaccuracies
  were fixed, and a comment implied that the critical change is to switch
  the rounding mode to to-nearest, with a switch of the precision to
  extended at no extra cost.  Actually, the errors are very large (ucbtest
  finds ones of several hundred ulps), and it is the switch of the
  precision that is critical.
  
  Another comment was wrong about NaNs being handled sloppily.
