I appreciate all the pointers and ideas. I ended up finding a solution
(instead of learning it myself, but that's okay - since I actually
learned more from the responses here) which is now in my .emacs file:

(defun uniquify-region (beg end)
  "remove duplicate adjacent lines in the given region"
  (interactive "*r")
  (goto-char beg)
  (while (re-search-forward "^\\(.*\n\\)\\1+" end t)
  (replace-match "\\1")))

(defun uniquify-buffer ()
  (interactive)
  (uniquify-region (point-min) (point-max)))

Thanks again for the help!
