Doc: Describe CREATE INDEX deduplication strategy.
The B-Tree index deduplication strategy used during CREATE INDEX and
REINDEX differs from the lazy strategy used by retail inserts. Make
that clear by adding a new paragraph to the B-Tree implementation
section of the documentation.
In passing, do some copy-editing of nearby deduplication documentation.
