With this patch applied, we end up with:
           if (strcmp(basedir, "-") == 0)           {
#ifdef HAVE_LIBZ               if (ztarfile != NULL)                   gzclose(ztarfile);
#endif           }           else           {
#ifdef HAVE_LIBZ               if (ztarfile != NULL)                   gzclose(ztarfile);               else
#endif               {                   if (fclose(tarfile) != 0)                   {
fprintf(stderr,_("%s: could not close file
 
\"%s\": %s\n"),                               progname, filename, strerror (errno));
disconnect_and_exit(1);                  }               }           }
 

I think it would make sense to rearrange that so that we don't have
two tests for ztarfile != NULL; do that test first, and then if it
fails, do the strcmp after that.

Also, if we're going to test the return value of fclose(), shouldn't
we also be checking the return value of gzclose()?
