PATCH: bzip2 support for _tar, more tar problems

[Clint Adams <schizo@debian.org>]

tar xvzCf /tmp archiv<TAB> will not complete to archive.tar.gz;
instead it attempts to untar /tmp in search of archive within.
There should probably be a sanity check first to avoid untarring
directories, and then _tar should recognize the -C and pass
-W /tmp to _files in _tar_archive.

tar --directory=/tmp xvzf archiv<TAB>, on the other hand,
will work, but it is merely doing a _path_files -W /tmp,
thus losing all the smarts it would have without the
--directory.  This should also be calling _tar_archive
which in turn should do a -W /tmp.

Unfortunately, _tar_archive is counting on $1 containing
the flags; I think _tar_archive should take these as
arguments.
