bug#31723: 26.1; next-logical-line different behaviour when global-display-line-numbers-mode is on

[Maxim Kim]

1. open emacs with `runemacs.exe -Q`

2. add some text to the scratch buffer:

;; This buffer is for text that is not saved, and for Lisp evaluation.
;; To create a file, visit it with C-x C-f and enter text in its buffer.

Hello WORLD, this is barebone EMACS here.
And next-logical-line function behaves strange when
global-display-line-numbers-mode is activated.

3. activate global-display-line-numbers-mode

4. put your cursor on the blank line above ‘Hello WORLD...' row:

;; To create a file, visit it with C-x C-f and enter text in its buffer.
<<CURSOR ON COL 0>>
Hello WORLD, this is barebone EMACS here.

5. press C-n to go-to ‘Hello WORLD’ row, cursor is on ‘H' letter

6. invoke ‘next-logical-line' interactive command with M-x
next-logical-line, your cursor will be on the second word of the
next row (marked as <<n>>):

Hello WORLD, this is barebone EMACS here.
And <<n>>ext-logical-line function behaves strange when



Without global-display-line-numbers-mode cursor moves to the same column
on the next row (of course if there are enough columns for that).


This behaviour breaks multiple cursors package for me -- when I try to
create several cursors for consequent rows.
