 Tells @command{tar} to create a new directory beneath the extraction directory
-(or the one passed to @option{-C}) and use it to guard against tarbombs.  The
-name of the new directory will be equal to the name of the archive with the
-extension stripped off.  If any archive names (after transformations from
-@option{--transform} and @option{--strip-components}) do not already begin with
-it, the new directory will be prepended to the names immediately before
-extraction.  Recognized extensions are @samp{.tar}, @samp{.taz}, @samp{.tbz},
