Hi,

this patch increases the robustness of tars file descriptor handling when
calling gzip. Without this patch it is not possible to use tar to create
a gzip compressed tar archive in an environment where fd0 has been closed.
The file for the tar archive would be assigned to fd0 and overwritten by
the first call to xmove_fd in vfork_compressor.


Greetings,

Tobias
