distinct name for whatwg's latin1

Hi Anne.

We spoke about this ages ago, but I'm trying to bring some closure to it.
http://www.unicode.org/mail-arch/unicode-ml/y2014-m01/0046.html

Given that I won't be able to budge Guy Steele on updating
windows/cp1252.txt[1], it seems we should give a distinct name to the
whatwg's definition of windows-1252[2].

This does happen to match the cp1252 definition labeled as "bestfit1252".
http://unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit1252.txt

My goal is to eventually have something in the python stdlib that we can
use to implement this spec.
Of course I'll need to first implement it as a third party, that's no issue.
I'd like to pick a name that's widely agreeable, so this can be promulgated
beyond me and my company.
Also, we've previously agreed that unicode.org and whatwg/encodings
disagreeing on what "windows-1252" means is too confusing. [3]

Possible names are:
 * web-1252 -- previously proposed by yourself
 * bestfit-1252 -- referring to the above "bestfit" document
 * whatwg-1252 -- the traditional format, with defining organization first
