(svn r9728) -Fix r9086: [win32] For some keyboard layout the 'console' key is a dead-key. It needs to be pressed twice to have an effect but the console is then opened and closed on the 'same' keypress (2 WM_CHAR events). So skip the first WM_CHAR generated to restore the 'console' key functionality.
