Log Message:
	On systems that lack the O_NOFOLLOW open(2) flag, check in
	sudo_edit_open() whether the path to be opened is symlink before
	opening it.  This is racey but we detect losing the last post-open
	and it is better to fail early if possible.  When editing a link
	to a non-existent file, a zero-length file will be left behind but
	it is too dangerous to try and remove it after the fact.
	Bug #753
