[BUG] unexpected behaviour on sub-list

[BUG] unexpected behaviour on sub-list

[Phil]

Hello,

I'm reporting this bug on Org mode version 9.7.6.
It was in already in 9.5.

    - here is a list
      with a sub list

      - like here ;

      and then text (<- this will be deleted)
    x

  1) Trying to insert an other item above,
     by suppressing the "x", and hitting M-RET,
     if there's no text after, the command gets stuck
     in org-list-struct-apply-struct.

     file:~/.emacs.d/repos/org/lisp/org-list.el::1968
     Very likely, needs to check if forward line returns 0
     otherwise it will keep looping.

     #+begin_src patch
- (while (< (point) down)
+ (while (and ( < (point) down) (not(> lines-left-to-move 0)))
    #+end_src

     file:~/.emacs.d/repos/org/lisp/org-list.el::1982
     #+begin_src patch
  - (forward-line)))
  + (setq-local lines-left-to-move (forward-line)))))
     #+end_src

  2) after a break, C-g, or if there is some text,
     the previous paragraph is killed and the list
     structure re/dis-organized.


Cheers,

Phil

Confirmed.
Potentially a duplicate of https://list.orgmode.org/orgmode/v3up5d$oc4$1@ciao.gmane.io/

Thanks for looking into the causes!
I will look closer into this later.
