Comment 1 for bug 1393053

In the current trunk, pressing backspace moves to the parent of the background directory of the view. For Icon view, List view and unexpanded Miller View this is what is expected. However, if you have an expanded Miller View, pressing backspace will move to the parent of the leftmost directory displayed, not the parent of the rightmost directory. This is because, at the moment, expanded Miller View directories are regarded as analagous to expanded rows in List View. However, as there is more than one bug report related to this behaviour we should consider changing it.
