Summary: CommandLineToArgvW bug with empty lpCmdLine
           Product: Wine
           Version: 1.1.17
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: shell32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

CommandLineToArgvW returns the wrong NumArgs (2 instead of 1) when an empty
lpCmdLine is passed:

How to reproduce
================
int nNumArgs = 0;
LPWSTR *Argv = ::CommandLineToArgvW(L"", &nNumArgs);
if(Argv)
{
  ASSERT(nNumArgs == 1);

if(nNumArgs == 2)
  {
     // Access violation
     wprintf(Argv[1]);
  }
}

MSDN Documentation on how to handle empty lpCmdLine
===================================================
"If this parameter is an empty string the function returns the path to the
current executable file."
