Yeah, a triple is the atom in RDF (in some sense) and it is
self-identifying.  I've asked before but still wasn't sure what the
appropriate API would be.

Maybe model.replace_statement(old_statement, new_statement)

or maybe something more specific:
  model.update_statement_object(old_statement, new_object)
but that seems rather specialised.

Either one would mean a lot of internal redland changes in order to make
this replace function as atomic as possible for all redland storages.
