I have been using the following kluge extensively for a long time. I
mainly use it in tables, but it is also useful for duplicating a line
that contains no tabs:
(defun ditto ()
"In a table, duplicate the entry above."
(interactive)
(let ((track-eol) (goal-column (current-column)))
(skip-chars-backward "^\t\n")
(setq newplace (point-marker))
(previous-line 1)
(setq oldplace (point-marker))
(skip-chars-forward "^\t\n")
(setq entry (buffer-substring oldplace (point)))
(goto-char newplace)
(skip-chars-forward "^\t\n")
(delete-region newplace (point))
(set-mark (point))
(insert entry)
)
)
