However, the user can easily make trac give you a backwards diff, for which the output is confusing (a change where text was deleted says that text was added instead). I suggest something like Wikipedia's interface, where it's impossible to see this kind of diff. Another option would be to provide a warning to the user if they tried that, or to detect it and show a forward diff. If there is a real reason to show a backwards diff, perhaps a special option could be enabled somewhere...
