This "No changes" was meant as a hint

Well, you edited you tree to look exactly like it already is.

Exactly.

it was not a noop patch before you resolved the conflict.

Well... This one kind of hard: git-rebase _cannot_ know whether it is
safe to just drop all changes in the index and work tree (you could
have made the changes on purpose). It was decided not to drop
anything. You always can do

    $ git reset --hard # kills all changes in index and work tree
    $ git rebase --skip

(or maybe git-rebase is just too careful...)

Yes. It was the last commit. You were just too unlucky to hit all the
hard cases your first day.
