--- Comment #5 from Stefan Dösinger <stefan at codeweavers.com> ---
So I looked into what the correct way might be to set this. From searching the
Windows registry it seems that HKLM/Software/Microsoft/Windows
NT/CurrentVersion/ProfileList, value name ProgramData contains the value that
gets assigned to %ProgramData%. set_additional_environment in
kernel32/process.c already handles other values in this registry key.

Finally
https://msdn.microsoft.com/en-us/library/windows/desktop/dd378457(v=vs.85).aspx
suggest that FOLDERID_ProgramData now points to %ProgramData% instead of
%ALLUSERSPROFILE%\Application Data

What I am not sure about is how the existing values in the above mentioned
registry key are created. I can create the ProgramData value via
loader/wine.inf, but I am not convinced this is the correct way.
shell32/shellpath does not expand environment variables, so changing the
existing "Application Data" string does not do the right thing, and having the
string redundantly doesn't seem to be the correct approach either.
