    gmarkup: Change how we detect that a subparser should be pop:ed
    
    We used to store a pointer to the element name and when a tag was
    closed the element name was pointer-compared. However, some
    future work will make these strings possibly shared between
    elements, so instead we compare for equality on the GSList node
    in the subparser stack.
    
    This should not affect behaviour in any way.
