Hi Tom,

I had to change the name of the hook, "midprocess" does not do
it justice.  I'm not sure if you really want to do this after the
protection stuff, because it will limit the processing of your
include files.

I have now added a few more hooks at strategic locations in the
preprocessing code, please take your pick from the hooks I am listing
below.  If you do need the hook in the position where you put it,
let me know and I will add another one.

(defvar org-export-preprocess-hook nil
  "Hook for preprocessing an export buffer.
Pretty much the first thing when exporting is running this hook.")

(defvar org-export-preprocess-after-include-files-hook nil
  "Hook for preprocessing an export buffer.
This is run after the contents of included files have been inserted.")

(defvar org-export-preprocess-after-tree-selection-hook nil
  "Hook for preprocessing an export buffer.
This is run after selection of trees to be exported has happened.
This selection includes tags-based selection, as well as removal
of commented and archived trees.")

(defvar org-export-preprocess-before-backend-specifics-hook nil
  "Hook run before backend-specific functions are called during  
preprocessing.")

(defvar org-export-preprocess-final-hook nil
  "Hook for preprocessing an export buffer.
This is run as the last thing in the preprocessing buffer, just before
returning the buffer string to the backend.")
