Surely it does.
Also, tip_oids_contain() uses unmatched and newlist only on the
first call, but the internal API this patch establishes gives an
illusion (confusion) that updating unmatched and newlist while
making repeated to calls to this function may affect the outcome of
tip_oids_contain() function. In fact, doesn't the loop that calls
this function extend "newlist" by extending the list at its tail?
