[issue2534] Can't commit: Python 2.7.1 breaks "editor" in win32

New submission from Edwin Brown <Edwin.Brown at gmail.com>:

Software Versions
Mercurial 1.7.2 on Win32
Python 2.7.1 from python.org

Configuration
Mercurial.ini
[ui]
editor = C:\emacs-23.2\bin\emacs.exe -Q -nw

After upgrading to Python 2.7.1 it is impossible to get an editor to work 
with windows due to changes in the way python invokes the cmd. In Python 2.7 
and previous the editor entry works perfectly. With 2.7.1 Mercurial just 
issues the following error 

The filename, directory name, or volume label syntax is incorrect.
abort: edit failed: emacs.exe exited with status 1. 

This is not confined to any particular text editor. It's even broken with 
just HGEDITOR set to Notepad. It looks like python now inserts some extra "" 
in the cmd /c string. 

Not sure if you guys want to account for this or talk with the python folks. 
The only workaround I've found is to bypass the editor entirely and use -m. 
I've also rolled a machine back to 2.7 and that works properly.
