Your recipe should work, assuming the file was added in r100 and never
changed or copied afterwards. You may pass --deltas to 'svnadmin dump'
(no reason not to). It'll offset r101:r200 revnums by one in the new
repository.
Another way is to use svnsync with path-based authz blocking the file
(and all its copied) from the sync user.
