    Fix test failure with Rust 1.18 and 1.19
    
    With Rust 1.18 and 1.19, I saw some test suite failures.  They were
    all of the same form -- Box seems to be qualified in the output now,
    like:
    
      print box_some
      $64 = core::option::Option<alloc::boxed::Box<u8>>::Some(0x7ffff6c21018 "\001\000")
    
    ... where the test was expecting Option<Box<u8>>.
    
    This patch fixes the problem in a way that should work with earlier
    versions of Rust.
