flags: also test merging a rename with and exec flag change

This case is currently buggy and was not tested. This is probably a quite old
regression. The next changeset fix this case. Move exec+rename related bug will
gain a test later.

To highlight the expected behavior the currently missing line are marked with (false !)
and the bad one with (true !)

note: we should probably gain explicit "test bool" for this usecases.
