FWIW, this is not the current behaviour that I see:

      - C-c C-t replace the buffer contents with the text version
      
      - C-c C-c, DocView switches back to the "edit" view: the raw
        content of a PDF for instance is displayed into the buffer.

      - another C-c C-c, DocView switches to the "display" view where
        you see the images again

Maybe while here, we should clarify how DocView cycles through those 3
view: display, edit and text.  Or maybe, there is no 3-states cycling
and the "text contents" view is just considered a "side" view.  WDYT?
