The diff --old -new syntax allows for limiting the diff to one or more
children of the diff targets. But it doesn't allow for excluding
children, except by enumerating all desired children.

For now, I would suggest using some 3rd party diff post-processing
tool to filter unwanted child paths from the output. One such tool is
filterdiff from patchutils, see http://cyberelk.net/tim/software/patchutils/

I would not mind seeing this functionality in Subversion but I don't
think it is very important. Why do you really need it?

I don't see how excluding subranges from the revision range being diffed
could be useful, or even well defined in the general case.
I suspect Brad came up with this idea because he already knows that the
unwanted revision range only affects a particular path within the diff
target. To me, it seems more natural to be filtering by path in this case,
rather than by revision numbers.

Also, depending on what kind of information you really want to obtain
by looking at the diff output, it is possible that using 'svn log --diff'
(new in Subversion 1.7) instead of 'svn diff' would be more useful than
any of the above.
