Thank you for the patch, Anatoly. Since it really does look
quite harmless, I have imported it into the archive without
consulting with Loic first; the new version should show on
the site any moment now. (I have edited out the "@patch1
..." line, though: that directive doesn't exist in the
formatting software.)

Loic, could you please let me know if you disagree with this
change in any way?
