After adding some code for reducing the overall memory consumption in
revision b4bc497, a number of spurious rebuilds was observed by different
people. The problem was, that the value of the Node.changed() method got cached
too early for File nodes.
This test verifies that the changed() function works properly, especially
in connection with auto-generated sources, combined with an explicit Depends().
