Improve nbtree README's LP_DEAD section. The description of how LP_DEAD bit setting by index scans works following commit 2ed5b87f was rather unclear. Clean that up a bit.
Also refer to LP_DEAD bit setting within _bt_check_unique() at the start of the same section. This mechanism may actually be more important than the generic kill_prior_tuple mechanism that the section focuses on, so it at least deserves to be mentioned in passing.
