This reminds me of something: it may be coincidence, but up until now
(until 1.7.x that is) 'svnlook changed -rX' and 'svnlook diff -rX'
presented the files in the same order. I like this behavior, because
it's nice when composing post-commit emails: the list of changed files
on top, followed by the actual diff ... both following the same order.

Anyway, no biggie, all I'm saying is: +1 for introducing some stable
ordering here ...
