Diff update does not work after [1768]

[Emmanuel Blot]

I may have missed a point, but it seems the last changeset broke the diff feature.

The get_diff_options(req) method checks for 'update' key which is not produced by the wiki.cs template anymore.

A quick patch like the following one may be one solution:

Index: templates/wiki.cs

      <input type="submit" value="Update" />
     </div>
    </div>

Fixed in [1769].
