From: dnljms_at_[hidden]
Date: 2011-11-30 03:21:59
Author: danieljames
Date: 2011-11-30 03:21:58 EST (Wed, 30 Nov 2011)
New Revision: 75744
URL: http://svn.boost.org/trac/boost/changeset/75744

Unordered: `emplace` cleanup.
- Always construct iterator in detail for consistency.
- Move 0-argument emplace to start of overloads.
