Proposed resolution:

Remove the CopyConstructible requirement. Specifically, replace 25.3.7, p1 with

-1- Requires: Type T is LessThanComparable ([lessthancomparable]).

and replace 25.3.7, p4 with

-4- Requires: Type T is LessThanComparable ([lessthancomparable]).

The requirements in 25.3.7, p1 and 4 call for T to satisfy the requirements of LessThanComparable ([lessthancomparable]) and CopyConstructible ([utility.arg.requirements]). Since the functions take and return their arguments and result by const reference, I believe the CopyConstructible requirement is unnecessary.
