  comment:    According to sources found on the internet, the magic key of tar files
              should be "ustar" followed by \\\\x00.

              Using ex. tar-1.34 from Debian 12 or 7z-25.01 on Windows, these
              programs write a space \\\\x20 instead of \\\\x00.

              So instead of using the following line to match tar files  ````  }
              elseif { $binary && [string range $test 257 262] == "ustar\\x00" }
              lappend type compressed tar  }  ```  one should use for example a
              statement like this:  ```  } elseif { $isBinary && [string range $test
              257 261] eq "ustar" } {  set shouldBeNull [string index $test 262]  if
              { $shouldBeNull eq "\\x00" || $shouldBeNull eq "\\x20" } {  lappend
              type compressed tar  }  }  ```
