Sorry, it still is not completely clear to me... I would be very glad if
you could detail better what happens when I tree-filter.  From what you
say I get the impression that no file should get a new blob.  As a
matter of fact, most do (and that is why at the very beginning I thought
that --tree-filter true would have been sufficient)... only a few do not
get the new blob.

And if I experiment filter-branch again, with exactly the same
parameters, apparently some of the files that did not get the new blob
in the beginning do...  which looks completely weird.

The attributes are in the info subdir of .git, so the brute force
approach should be fine.  I guess that it does not make any difference
wrt to a

    find ./ -type f -exec touch \{\} \;

apart from looking slightly more aggressive to the index (and faster) or
does it?
