Log Message:
	run_command: run editor in foreground if visudo is the foreground process

	The command is now always run in its own process group.  If visudo
	is run in the foreground, the command is run in the foreground too.
	Otherwise, run the command in the background.  There is a race
	between the tcsetpgrp() call in the parent and the execve() in the
	child.  If we lose the race and the command needs the controlling
	terminal, it will be stopped with SIGTTOU or SIGTTIN, which the
	waitpid() loop will handle.
