BTW, I noticed that the first item of etc/TODO describes exactly the
same need:

* Small but important fixes needed in existing features:

** Fix the kill/yank treatment of invisible text. At the moment,
  invisible text is placed in the kill-ring, so that the contents of
  the ring may not correspond to the text as displayed to the user. It
  ought to be possible to omit text which is invisible (due to a
  text-property, overlay, or selective display) from the kill-ring.

It would be quite easy to implement: for example, to create a new
boolean option, e.g. `yank-as-displayed', and in `insert-for-yank-1'
to handle it by deleting the text with `invisible' property and
replacing the text with `display' property by the display value
(though, I don't see how overlays could be handled here since they
are not saved with the text in the kill-ring).

Is it a right way to implement this?  This could be implemented now
given that it is described as "small but important fix".
