The diff output is partly a choice made by the client itself. If we
operate on a non-root node:

   svnadmin create repo
   svn mkdir -mm file://`pwd`/repo/A
   svnmucc -mm -U put repo/format file://`pwd`/repo/A/f
   svnmucc -mm -U put repo/format file://`pwd`/repo/A/f
   svnmucc -mm -U propel p file://`pwd`/repo/A

The diff reports that the server sends to the client include an open-dir
for /A in -c3 and an open-file for /A/f in -c4. The diff reports have
no equivalent of log's text-mods/props-mods but they do communicate that
a new node was created. The diff client could choose to output some
sort of "new node" message.

'svnlook changed' has behaviour that is somewhere between log and diff
above: it indicates a change for for the text no-op -r3 but no change
for the property no-op -r4.
