New issue 26 by dosu...@gmail.com: expand_expression_to fails to roundtrip  
properly
http://code.google.com/p/oboformat/issues/detail?id=26

expand_expression_to fails to roundtrip properly.  I think the problem is  
OWL to OBO.

e.g.

This line of OBO

expand_expression_to: "<http://purl.obolibrary.org/obo/RO_0002131> some  
(<http://purl.obolibrary.org/obo/GO_0045202> and   
<http://purl.obolibrary.org/obo/BFO_0000050> some ?Y)" []

gets translated into OWL:

  <obo:IAO_0000424  
rdf:datatype="http://www.w3.org/2001/XMLSchema#string">&lt;http://purl.obolibrary.org/obo/RO_0002131&gt;  
some (&lt;http://purl.obolibrary.org/obo/GO_0045202&gt; and   
&lt;http://purl.obolibrary.org/obo/BFO_0000050&gt;  
some ?Y)</obo:IAO_0000424>

But gets translated back as

expand_expression_to: <http://purl.obolibrary.org/obo/RO_0002131> some  
(<http://purl.obolibrary.org/obo/GO_0045202> and   
<http://purl.obolibrary.org/obo/BFO_0000050> some ?Y)

i.e.- no quotes or terminal []
