Without this, the program segfaults because the necessary setup for
applying a text delta hasn't been set up. Perhaps I should explain
this in my commit message?

This concept took me some time to wrap my head around: I had to stuff
the replay_baton with the editor/ editor_baton so that I could set
them for use in the callback functions. Comment moved to a later

Yes. Fixed now. I moved it this change to the next patch.
