    Fixed bug#20825: rollup puts non-equal values together · 0c9f941b

    Fix for bug 7894 replaces a field(s) in a non-aggregate function with a item
    reference if such a field was specified in the GROUP BY clause in order to
    get a correct result.
    When ROLLUP is involved this lead to a wrong result due to value of a such
    field is got through a copy function and copying happens after the function
    evaluation.
    Such replacement isn't needed if grouping is also done by such a function.
    
    The change_group_ref() function now isn't called for a function present in
    the group list.
