[developers] Preprocessor, again

[Ann Copestake]

a partial and very temporary hack around is as follows:

in :lkb

(defun sort-edges-by-from (edges &key addressing)
  (sort (copy-list edges)
	'<
	:key (lambda (x)
	       (point-to-char-point (or (saf-edge-from x) "0") addressing))
	))

I assume that Ben will attend to the underlying problem, which appears to be 
in his code, though I am very surprised this issue didn't surfaced earlier,
