Hm, I must admit that I don't understand the change in line-move, or
better said the context in which it was made.  So if I fix this I
probably break some optimization.

I have a simple recipe now, though.

emacs -Q

Insert and eval this function:

(defun hansi ()
  (insert "line 1\n")
  (insert (propertize "+invisible 1\ninvisible2-\n" 'invisible t))
  (insert "line 2\n"))

M-: (hansi) RET
C-p
C-x =
=>
Char: + (43, #o53, #x2b) point=330 of 365 (90%) column=0

That's something for Eli, I'd say.
