The preferred form is a diff -u as a text attachment.  svn diff is 
basically diff -u, but has the advantage of telling us exactly what

But for something as simple as this, inline is fine, thanks.

[The main reason for wanting an attachment is that once lines get 
wrapped or tabs expanded, the noise can far exceed the signal.]
