For comparing the source of two latex files (as opposed to producing a
dvi/pdf etc which shows the differences) I find the emacs ediff-files
command very useful.

In the case where line breaks have changed, I use
ediff-regions-wordwise, or the following wrapper:

(defun find-whole (f1)
  (find-file f1)
  (mark-whole-buffer)
  (current-buffer))

(defun eword-files (f1 f2)
  "Find files, mark whole buffers, and run ediff-regions-wordwise
   on them."
  (interactive "fFirst file: \nfSecond file:")
  (ediff-regions-wordwise (find-whole f1)
			  (find-whole f2)))
