+ application. mintty doesn't use Windows Console for it's screen
+ I/O, so the native Windows _isatty doesn't recognize it as
+ character device. But we can discover we are at the end of an
+ Pipe and can query the server side of the pipe, looking whether
+ or not this is mintty.
+ For now we terminate the program if we discover that situation.
+ Althogh in theory it would be possible, to remotely manipulate
+ the terminal state of mintty, this is out of scope for now and
+ not worth the significant effort.
