Right, I am forgetting about this. And the difference is in the size of the files:
[s2@katleriai SRPMS]$ wc -l ~/.wine/config ~/.wine/system.reg 256 /home/s2/.wine/config 4946 /home/s2/.wine/system.reg 5202 total
Text editor for the registry tweaking isn't an easy choice for me, because I don't like searching for one particular line through the 5000 of others.
What then should I do walking this way is:
1, to export file; 2, to edit it; 3, import it back.
Maybe we should fork the Wine/Config branch into a separate .reg file to appease those who want to edit it using a text editor. That would make the switch from config file -> registry less obvious. Not exactly the same of course, no comments for one, no defaults to show you what they are for another, but it might be an improvement?
