I very much like the idea behind this.  Unfortunately, it's extremely
difficult to discover this feature by accident.  It took me several
minutes to figure out that there was a new "diff to ..." link in each
changelog entry, after I had selected one changeset as the reference
changeset.  All the switches of page context (changelog list ->
changeset view -> changelog list -> diff view) make it very confusing,
I'm afraid.

It would be nice to have selecting a reference changeset and the
changeset to diff against be possible in a single window.  How to do
that without putting a radio button and "diff" link next to each entry
in the changelog list, I don't know.  But that would make it much
simpler to discover and use.

Sorry for the mixed feedback.
