Is that what %o stands for?  If so, I apologize for not looking
deeper: relative file names without any leading directories of course
cannot have any such problems.  (Does that mean that this command will
only support producing the tarball in the same directory which Dired
displays?)

Sounds OK to me, but maybe wait for a while for others to speak up.

Thanks.
