Sigh. The tar code is nasty and tangled, and seems like it would need an
extensive rewrite to propagate back this error. Look at tar.c line 853:
while (get_header_ptr(tar_handle) == EXIT_SUCCESS);
/* Check that every file that should have been extracted was */
while (tar_handle->accept) {
In this case, get_header_ptr should be a function pointer to
get_header_tar_gz(), which returns either EXIT_SUCCESS or EXIT_FAILURE.
EXIT_FAILURE means "couldn't extract a file". Could be end of file, could
be an error, it doesn't distinguish.
I need to rewrite this to just fork off a copy of gzip for both read and
write, but that's not happening in 1.2.0...
