Re: [PATCH 0/1] MR6605: cmd: Call ReadConsoleW() only with standard input handles.

[eric pouech (＠epo)]

the std input handle can be anything:
- it's by default the input handle from which cmd.exe has been created (someone could invoke cmd.exe with "cmd /c foo.bat < COM1" and you get a serial line handle)
- and it's changed with any redirection (so < COM1, < NUL, < CON would set a CHAR file type); and perhaps tomorrow | (piping) commands will be implemented with (named) pipes

Piotr's suggestion is even cleaner (as it will not accept other CHAR devices)

Note: we need to keep ReadConsole (instead of ReadFile) when we implement completion of commands
