The answer might be somewhere in this list's archives. ISTR that it
was something like:

   "If a file was deleted, it might be not interesting to see all the
    lines that went away, since they're gone now -- so we should
    support --no-diff-deleted in 'svn'. But if a file is added, you
    usually want to see all the new lines, because they exist now, so
    --no-diff-added would be less useful."

While this convinces me that --no-diff-added is usually less useful
than --no-diff-deleted, that doesn't mean never useful, and I'd be
happy to see a patch adding that option.

You'll want to read http://subversion.tigris.org/hacking.html
and especially http://subversion.tigris.org/hacking.html#patches.

Best,
