The testing approach taken by Arwin seems solid enough in my book.

If that's what's worrying you, then let's postpone it to after 1.7.
That's fine with me. It means that we'll have to write a new diff
that fits on top of the post-1.7 update editor code. But if stability
concerns outweigh this, I can live with that.

I haven't yet seen any good suggestion for an alternative approach.
Dry run implies carrying out every step made during an update expect
making modifications to the working copy. The suggestion to put dry-run
into a separate editor is even worse because it duplicates at lot more
conditionals (for update logic) in a new place than this patch is adding
to existing places.

If there is a cleaner way to do it, fine. Maybe Arwin would like to learn
about this better approach and try to implement it, for update and for merge.
But is there?
