well, this *is* a bug!  i noticed it when testing stuff to answer pete's
question, but ignored it.  then we pete mentioned it again, i started
poking around.  can't find any mention of it anywhere.  however, the
tar man/info page at gnu.org says
  "if you list no member names, nothing will be deleted"
and this is clearly violated.  as pete noticed, it also destroys the
archive if a member name is not actually a member.

i reported this to bugzilla.redhat.com for version 7.1 and got a
quick reply that "it works in 7.3."  however, i just tested it with 7.3
and it's broken there, too; i added a comment to this.

FYI, this is tar-1.13.19-4 on RH 7.1 and tar-1.13.25-4 on RH 7.3.

shawn.
