Bug ID: 37575
           Summary: regedit: duplicated null charactors
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: programs
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

regedit.exe seems add duplicate null charactors when type of value is "str".

$ echo "[HKEY_LOCAL_MACHINE\SYSTEM]" $'\n''"TestKey"=str:"a"'|wine regedit -
  $ wine C:/Ruby200/bin/ruby.exe -rwin32/registry -e
'Win32::Registry::HKEY_LOCAL_MACHINE.open("SYSTEM") do |reg| p
reg.read("TestKey") end'
  [1, "a\u0000"]

$ echo "[HKEY_LOCAL_MACHINE\SYSTEM]" $'\n''"TestKey"=hex(1):61, 00, 00,
00'|wine regedit -
  $ wine C:/Ruby200/bin/ruby.exe -rwin32/registry -e
'Win32::Registry::HKEY_LOCAL_MACHINE.open("SYSTEM") do |reg| p
reg.read("TestKey") end'
  [1, "a"]

I guess this is due to programs/regedit/regproc.c.

static LONG setValue(WCHAR* val_name, WCHAR* val_data, BOOL is_unicode)
  {
      ...
          val_data[dwLen-1] = '\0'; /* remove last quotes */
          lpbData = (BYTE*) val_data;
          dwLen++; /* include terminating null */
      ...
  }

"include terminating null" should be discarded because "remove last quotes"
already add terminating null.
