Changing relevant versions in docnotes cannot be traced

I got a series of modification notifications for some docnotes I made. I stared at the diff between the new and the old version, but I could not see any differences. It turns out that the only difference was that an applicable version was added. However, that cannot be seen in the version diff.

I think that this information should be present somehow in the diff, so you can actually see what the change was all about.
