I thought the diffs were computed on the server side and applied to the
client files in a merge.

What would you expect 'svn diff ...' to show? And the deltas stored for
each version would be as large as the file itself.

A version control system that can't do efficient diffs will just be a
clunky backup system that makes a full snapshot copy for every change
(which could be done into an encrypted file if that's what you want).
