        Merge a ``base`` item with an ``override`` item.

        Both ``base`` and ``override`` are converted to dictionaries if possible.
        Sets are converted to dictionaries with the sets entries as keys and
        Ellipsis as values.

        Each key-value pair existing in ``base`` is merged with ``override``,
        while the rest of the key-value pairs are updated recursively with this function.

        Merging takes place based on the "union" of keys if ``intersect`` is
        set to ``False`` (default) and on the intersection of keys if
        ``intersect`` is set to ``True``.
