Log Message:
	visudo: restore controlling terminal after running the editor.
	Otherwise, visudo will get SIGTTOU if it tries to write to the
	terminal after the editor finishes.  Also avoid races by setting
	the process group ID in both the parent and child, and grant the
	controlling terminal in the parent, not the child.
