It is currently proposed that insert, erase and rehash should be stable. Change insert(hint, value) so that it inserts at the end of a group of

equivalent keys (all the other functions were already stable).

     518. Are insert and erase stable for unordered_multiset and unordered_multimap?]]
 
-In this implementation, erase is stable. All inserts are stable, except for
-inserting with a hint, which has slightly surprising behaviour. If the hint
-points to the first element in the correct equal range it inserts at the end of
-the range, for all other elements in the range it inserts immediately before
-the element. I am very tempted to change insert with a hint to just ignore the
-hint completely.
+The current proposal is that insert and erase are stable - so they are here.
