Thanks very much for your patch. It seems fine to me, I've only one
question: You copied the comment about Yun's algorithm from the
sqrfree() function. But does the last sentence ("For completeness, we'll
also have to recurse...") really apply here? As far as I can see, it
should be removed.

You are correct, Richard! I am attaching the updated patches.

 Vladimir
