[Bug 12914] New: wineprefixcreate overrides custom entries in Explorer\\Shell Folders

http://bugs.winehq.org/show_bug.cgi?id=12914

Summary: wineprefixcreate overrides custom entries in
                    Explorer\Shell Folders
           Product: Wine
           Version: 0.9.59.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: tools
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I have been playing with specifying custom paths for user shell folders, in
order to be able to use the same wineprefix for multiple users (r/o C: drive,
r/w D:). But it seems that every time I run wineprefixcreate, it overrides some
of the paths specified in
[Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders].

I'll shorten this up for brevity:
arno@master:~$ wine --version
wine-0.9.59
arno@master:~$ rm -fr .wine
arno@master:~$ wineprefixcreate
Could not load Mozilla. HTML rendering will be disabled.
/home/arno/.wine updated successfully.
arno@master:~$ grep '\profiles\' .wine/user.reg 
"AppData"="C:\windows\profiles\arno\Application Data"
"Cookies"="C:\windows\profiles\arno\Cookies"
"Desktop"="C:\windows\profiles\arno\Desktop"
"Favorites"="C:\windows\profiles\arno\Favorites"
"History"="C:\windows\profiles\arno\Local Settings\History"
arno@master:~$ sed -i 's/(\profiles\\)arno/\1test/' .wine/user.reg
arno@master:~$ grep '\profiles\' .wine/user.reg
"AppData"="C:\windows\profiles\test\Application Data"
"Cookies"="C:\windows\profiles\test\Cookies"
"Desktop"="C:\windows\profiles\test\Desktop"
"Favorites"="C:\windows\profiles\test\Favorites"
"History"="C:\windows\profiles\test\Local Settings\History"
arno@master:~$ wineprefixcreate
Could not load Mozilla. HTML rendering will be disabled.
/home/arno/.wine updated successfully.
arno@master:~$ grep '\profiles\' .wine/user.reg 
"AppData"="C:\windows\profiles\arno\Application Data"
"Cookies"="C:\windows\profiles\arno\Cookies"
"Desktop"="C:\windows\profiles\test\Desktop"
"Favorites"="C:\windows\profiles\test\Favorites"
"History"="C:\windows\profiles\arno\Local Settings\History"

Also, the overrides that are displayed here do not come from userdef.reg
(tested by modifying userdef.reg), they appear to be coming directly from
[Software\Microsoft\Windows
NT\CurrentVersion\ProfileList]\"ProfilesDirectory"

I'm not sure what the intended behaviour of wineprefixcreate should be (I think
it should not modify existent keys, only add missing ones), but at least the
inconsistent behaviour is a bug.
