Yes. We should do ~query_fileowner() for all files in that dir
(and recurse to subdirs). For efficiency we should start with oldpkg,
because query_fileowner is not a fast operation (but the situation of
this thread is not common, so the speed is not so important here).
But this is not so trivial, we could consider NoUpgrade, ".pacsave"
stuffs too (and I may miss something here), if we want to _simulate_ our
transaction perfectly.
