Unified diff link broken on specific file/revision diff view
Clicking on the "Unified diff" linkt at the bottom of a diff page of a specific file for a specific revision doesn't work anymore.
For a SVN revision, it simply produces a 404 error page.
The unified diff link is badly formatted; instead of adding a
format query parameter, it seems that source:/tags/2.0.3/lib/redmine/views/other_formats_builder.rb#L26
format value is now appended at the end of the URI like a file extension.
