    Description

      Invalid command line parsing at QCoreApplication::arguments on MS Windows family: double backslashes not recognized.
      Compare argc/argv passed to main with result of QCoreApplication::arguments when command line is: 

      qtapp.exe arg1 "arg2" "\"arg3\"" "\\arg4\\" "\\\"arg5\\\""

      I found some rules of Windows command line parsing: http://www.autohotkey.net/~deleyd/parameters/parameters.htm#WINCRULES.
      Also I tried to make solution - see attached "QtCore_winmain_argv.patch" - but it's not complete.

      Try attached "qt_4_8_0_winmain_argv_bug.zip" (solution for MSVS 2010) in debug configuration to see bug (and try it after applying "QtCore_winmain_argv.patch" - bug will still be there).
