Hi,
When display-line-numbers-mode is on and the (point) is on the
beginning of line, posn-at-point returns a wrong value.
Reproducible in emacs -Q:
```
(save-excursion
(message "Without display-line-numbers:")
(display-line-numbers-mode -1)
(goto-char (line-beginning-position))
(message "column 0: %s" (car (nth 2 (posn-at-point))))
(forward-char)
(message "column 1: %s" (car (nth 2 (posn-at-point))))
(message "With display-line-numbers:")
(display-line-numbers-mode)
(goto-char (line-beginning-position))
(message "column 0: %s" (car (nth 2 (posn-at-point))))
(forward-char)
(message "column 1: %s" (car (nth 2 (posn-at-point))))
)
```
Output:
```
Without display-line-numbers:
column 0: 0
column 1: 19
With display-line-numbers:
column 0: 0
column 1: 114
```
On the bol, it returns zero but it should return (- 114 19)

Sorry, I forgot to mention that the interesting value is the X position.
Is it still related to count-lines ?

Sorry, my fault. Referred to a bug in count-lines, which occurs at BOL.
As its docu says, the return value may differ: "but can be one more if
START is not equal to END and the greater of them is not at the start of
a line."
Seems unrelated here.

Thanks, should be fixed now on the master branch.

OK, thanks for testing. I'm therefore closing the bug report.
