[Terry J. Reedy]

Terry J. Reedy added the comment:

Since Mike has not responded in more that a week, please go ahead.  Just put "“Original patch by Mike Short."  in the commit comments (if you can, otherwise add a separate comment).  Please add News blurb (see devguide) if you know how, with at least a title line.  Mike has signed the CLA, though it would not matter here since his patch is taken from my message and could be classed as trivial.
