    girepository: Clarify SimpleTypeBlob documentation
    
    The documentation comment for SimpleTypeBlob seemed to imply that a basic
    type was embedded if the reserved fields were nonzero. After examining the
    code, I believe that was actually due to some words missing, and the
    comment should say that the type is embedded if the fields are zero.
