Vincent, I think you understand the --incremental and --deltas option
intents, but for the sake of others in this thread, allow me to clarify:

   * With no options, the first revision dumped by 'svnadmin dump' will
     contain a complete listing of every directory and file in the
     repository, the files' fulltext contents, all properties, etc.
     Subsequent dumped revisions have the same but only for files and
     directories changed in that revision.

   * All that --incremental does is make that first dumped revision
     like the others by only representing the files/dirs changed in that

   * --deltas causes 'svnadmin dump' to use binary deltas instead of
     fulltexts to represent file contents.

Sadly, 'svnadmin help's usage message isn't very helpful, because it uses
"diff vs. fulltext" to describe for --incremental instead of "changed paths
vs. all paths".
