Revert "Stop btree indexscans upon reaching nulls in either direction."
This reverts commit d23165bbc306005f687756a20d9af807d665a1f2.
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.
