[Bug 17242] New: Regedit: Exported key names containing backslashes are not escaped

http://bugs.winehq.org/show_bug.cgi?id=17242

Summary: Regedit: Exported key names containing backslashes are
                    not escaped
           Product: Wine
           Version: 1.1.14
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

For example, exporting HKEY_LOCAL_MACHINE\System\MountedDevices in regedit will
write keynames as such:

[HKEY_LOCAL_MACHINE\System\MountedDevices]
"??\Volume{00000000-0000-0000-0000-000000000043}"=hex:2e,2e,2f,64,72,69,76,65,\
  5f,63,00

which cannot be imported by regedit - the correct output should have been:

[HKEY_LOCAL_MACHINE\System\MountedDevices]
"\??\Volume{00000000-0000-0000-0000-000000000043}"=hex:2e,2e,2f,64,72,69,76,65,\
  5f,63,00

which imports correctly.
