 I just tried the following which appears to show that it actually was
 fixed.  The default is still not to follow symbolic links as per the
 man page however, and I also tested extracting with -h and the same
 proper behavior was observed.  This thus probably was another bug
 specifically related to overwriting symbolic links with directories
 which was fixed since.
