[Bug 10077] New: [~] badly handled by WriteEnvironmentStrings make Photoshop CS2 installer clear the PATH instead of adding a directory to it

Summary: [~] badly handled by WriteEnvironmentStrings make
                    Photoshop CS2 installer clear the PATH instead of adding
                    a directory to it
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: Installer
          Severity: normal
          Priority: P2
         Component: wine-msi
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

By default [~] is translated to a NUL character however in
WriteEnviromnentStrings it should be translated into the current value of the
variable. Photoshop CS2 writes "[~];[CommonFilesFolder]Adobe\AGL" into the
PATH what in our current implementation results in the PATH being cleared
instead of appended.
