Log Message:
	* win/tclAppInit.c (sigHandler):  Protect from trying to close a
	NULL handle.

	* win/tclWinPipe.c (PipeClose2Proc, TclpCreateProcess):  Send a
	real Win32 signal (CTRL_C_EVENT) when the read channel is brought
	down to alert the child to close on its side.  Start the process
	with CREATE_NEW_PROCESS_GROUP to allow the ability to send these
	signals.  The following test case now brings down the child
	without the use of an external [kill] command.

	% close $p     <- now doesn't block in Tcl_WaitPid()
