What's the purpose of adding them to the Marshal output?

Would this information be displayed in gem list -d?

What would be in this field, just the license name, or the full text?

If just the name, we should add something to #validate to make sure  
that somebody doesn't paste in the entire GPL as this could incur a  
heavy bandwidth cost.  If it's the full text it probably shouldn't go  
in the Marshal output.
