This might be halfway intentional, since the description of the commit is: Emit an explicit document end indicator when there is a possibility of ambiguous parsing.

I think that on the root level the caller should be responsible if he uses dumped string in ambiguous way, since he can always request explicit_end.

Removing these lines removes the problem:

if hints[-1:] == u'+': 
    self.open_ended = True

The issue is: the caller should be responsible for emitting of a redundant 'end of document'. The caller is aware of the context (PyYAML is not). It is not convenient to massage the source code to get rid of unexpected output which reduces readability.
