Markus,

Yes, leaving rep sharing enabled is better for another reason that a file
sync agent is *likely* to encounter: someone renames a directory. Remember
I'm not using Subversion client tools to effect a commit.

If I were storing a CinemaDNG (RAW) movie in Subversion and my operation
was to cut one second from the movie, then I might expect deltification to
help. It the format were MP4/AVI (H.264), I struggle to believe that the
'saving' of the movie from the editor you performed the clip in is anything
close to idempotent. I could try to find out for sure, but it's a stretch.
