	By definition, if you are trying to detect WINE and this is successful - this 
is a bug. And there is no warranty that registry key you are testing doesn't
exist on Windows or exist on WINE (at least user can create it by hand in 
Windows registry or remove it in WINE registry; or after some time it might 
be changed/removed in WINE registry).
	If there is any bugs, please report them at http://bugs.winehq.org .
	If you decide to keep WINE-detection at least provide documented command-line 
keys to disable it. For example, I saw one application that tries to detect 
WINE and if this is successful it changes its behavior in some places and I 
prefer to disable that because modern WINE works much better that at the time 
the program (and its WINE-related workarounds) was created.
	In other words, any attempt to detect WINE, or, even worse, its version, is 
strongly discouraged practice (because relying on such a thing means relying 
on bugs).
	If you *really* require some workarounds ASAP, then you can give a user to 
choose (either in menu/options dialog or at first startup) does he/she use 
WINE or not - but this is also discouraged practice.
	Don't forget to report a bug if you found one!
