After applying LDR#149, forward_list now has 5 overloads of
insert_after, all returning an iterator.

However, two of those - inserting a single object - return "An
iterator pointing to a copy of x [the inserted object]" while the
other three - inserting zero or more objects - return an iterator
equivalent to the position parameter, pointing before any possibly
inserted objects.

Is this the intended change?


I don't really know what insert_after(position, empty_range) should
really return, but always returning position seems less than useful.
