<pre>It's valid for the heterogeneous version of {map,set}::{equal_range,count} to
be called with something that compares equivalent to more than one key in the
container; the only requirement is that the keys of the elements be suitably
partitioned with respect to the heterogeneous key. (The motivating example in
N3465 is about finding the range for with a particular family name in a
set<name_entry>.) Thus, these versions cannot call
__{equal_range,count}_unique.
