Regedit output to STDOUT / force registry files sync

[Vit Hrachovy]

Hi,
I'm trying to find some elegant method to access registry keys added 
during one WINE session, i.e. without restarting WINE.

Test case description:
    1. Open WINE session
    	wineconsole --backend=user cmd
    2. During session, insert some new registry key
    	regedit new-entry.reg
    3. Try to access the new registry entry from bash
    	cat ~/.wine/system.reg |grep AutoHotkey
    	(fails)
    4. Close WINE session

I've found there was at times an option to save registry periodically, 
but this can't help me here.

This problem can be solved in two ways, both of them can be helpful:

a) Create small program to force sync of registry in memory with 
registry files - 'wineflushregistry'.

b) Enhance regedit to be able to output to STDOUT. By default registry 
search output is done to a specified file. It can be redirected to 
STDERR, though. (tested on 0.9.29, 0.9.33)

Enhancing regedit
-----------------

regedit /es 
"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App 
Paths\AutoHotkey.exe"

which will be similar to (non-functional)

regedit /e /dev/stdout 
"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App 
Paths\AutoHotkey.exe"
