OK, I submitted a request for enhancement to make --fuzzy --fuzzy do this:

That's a good point.  Wayne's main argument against doing fuzzy
matching in --*-dest directories was that it would be too slow.
However, fuzzy matching on a full destination directory containing the
previous snapshot takes the same amount of time as fuzzy matching on a
--link-dest directory containing the previous snapshot.

One might want fuzzy matching to visit some --*-dest dirs and not
others.  It seems that detect-renamed, if enabled, should operate on
the same subset of the --*-dest dirs as fuzzy matching.  Thus, maybe
there should really be alternate forms of the --*-dest options
(--fuzzy-*-dest) that enable both detect-renamed and fuzzy matching
for that dir.  Thoughts on this?
