The short answer is: Yes, it handles those extensions and will work for 
non-gnu tar.

The longer answer is:
untar.m calls unpack.m for all its operation.  unpack can handle the 
following extensions (alphabetically) .bz, .bz2, .gz, .tar, .tar.bz, 
.tar.bz2, .tar.gz, .tbz, .tbz2, .tgz, .Z, and .zip.

In what may be considered a bug (though I think it's a feature), untar, 
unzip, unzip, and bunzip2 will work for any of the file types.  The only 
caveat to this is that gunzip can work on a directory (recursively 
uncompressing all gzipped files), and that requires a bit of 
specialization (but you shouldn't be trying to untar a directory anyway).
