the one reason for gnu tar to do that is so that it can be a drop-in
replacement for those crappy versions.

on every non-linux machine i have to use, the first thing i do is
download and compile all the GNU tools including tar.  i then change
the PATH setting to include /usr/local/bin/gnu at the start.

if the GNU commands were not backwards-compatible then it would
be dangerous to do that.

i think that whatever we do is going to be broken somehow.

leaving it as -I means that GNU tar would no longer be a drop-in
replacement for a proprietary tar.

changing it to -j means that an upgraded GNU tar is no longer a drop-in
replacement for older versions of GNU tar.

both options suck.
