US 2 (006): 2.1.1: Update ranged-for-loop wording

[CaseyCarter]

Editorial Comment

The wording no longer matches the more thoroughly reviewed form in the C++17 Working Draft.

Proposed Change

Entirely replace this wording with the proposed wording for C++17.

2017-02-28 LEWG triage: LWG. (LEWG says yes, do it.)

[CaseyCarter]

Our base document is C++14. I think before we can do this we need to determine - possibly with advisement from CWG - if both versions of the wording are normatively equivalent. I certainly do NOT want to require implementations of C++14 + Ranges to implement any other normative differences to range-based-for other than the relaxation to enable sentinel delimited ranges.

[CaseyCarter]

CWG (in telecon) sensibly requests full text of the proposed change to the TS wording.

EDIT: Casey volunteers to provide that wording.

[CaseyCarter]

CWG in telecon approves the wording of the proposed change and is calling it tentatively ready. I am to get a P-number and submit it in the pre-meeting mailing to be moved in Toronto.

Awesome, thanks Casey!
