This one is easy, make tmp a directory, then build the tar file in that 
directory so the archive members don't include the tmp name, then just 
move the tar file to where it is needed...

tmp="$GIT_DIR/bundle_tmp$$"
references="$tmp/references"
pack="$tmp/pack"
trap 'rm -rf "$tmp"' 0 1 2 3 15

mkdir "$tmp" &&
echo "v1 git-bundle" > "$version" &&
------

# create the tar file, clean up
cd "$tmp" &&
tar cf bundle prerequisites references version pack &&
cd - &&
mv "$tmp/bundle" "$bfile" &&
rm -rf "$tmp"

I believe that as this works, tar needs only to understand c, f, and -O. 
It is easy enough to search for gtar and use that, or allow user to 
define TAR. So, I think this is a non-issue.
