AUCTeX contains the following pertinent comment:

;; Following lines are copied from `fill.el' (CVS Emacs, March 2005).
;;   The `fill-space' property carries the string with which a newline should be
;;   replaced when unbreaking a line (in fill-delete-newlines).  It is added to
;;   newline characters by fill-newline when the default behavior of
;;   fill-delete-newlines is not what we want.

I seem to remember that Emacs does a better job currently than AUCTeX
with regard to keeping text properties alive.  Some synching may be in
order but it would appear that it would be saner to change this for
filling in Emacs itself before starting to copy code into AUCTeX (or
calling the Emacs code if it's versatile enough) if that's your goal.
