[Bug 11020] New: winelauncher does not handle spaces in WINEPREFIX correctly

http://bugs.winehq.org/show_bug.cgi?id=11020

Summary: winelauncher does not handle spaces in WINEPREFIX
                    correctly
           Product: Wine
           Version: 0.9.52.
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: wine-loader
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In line 323 in winelauncher it tries to create the info_flag file with a touch.
If WINEPREFIX contains spaces this will fail.
This also allows for some kind of command injection with that variable.
