Revert "Stop btree indexscans upon reaching nulls in either direction."
This reverts commit ff41611ddcce36b8f87b73c65b78d8f71a157302.
As pointed out by Naoya Anzai, we need to do more work to make that
idea handle end-of-index cases, and it is looking like too much risk
for a back-patch. So bug #6278 is only going to be fixed in HEAD.
