Thank you for the detailed bug report.  First, I was able to come
up with a test case where the argument parsing was broken, and I
have fixed that in CVS.

I have also now fixed the problems with mis-handling of long filenames and
links.  Because I am trying to get a release out the door, and because I am
feeling lazy today, I have taken the simplest approach to the problem -- when
tar detects a file name longer then the field size, it now complains that a
long file name exists and then it now skips the long file (both when extracting
and when archiving).  So now, the user is warned (instead of the silent tarball
corruption that could occur before).

My appologies for the bug,

 -Erik
