[Rebuild] We're better off detecting splits and merges

I am really, really uneasy about that.
If we try and guess splits and merges - and that's all it can ever be, a
guess - then we will end up giving all manner of false negatives. It is
impossible to tell whether a new way with coincident (clean) nodes and a
coincident (accurate, factual) tag was actually derived from a previous,
now deleted way. If the nodes are clean and the tags are correct, you
really cannot assume that it is an infringement.
I would far rather we have no special treatment of splits or merges; and
that we make extra efforts in the first two weeks after the licence
change to accommodate any objections from people who claim that their IP
has been infringed by unintentionally carrying over a tag or two as a
result of a split.
