bug#55787: 29.0.50; inconsistent sort order with ls-lisp-version-lessp

[TAKAHASHI Yoshio]

Hi,

I encounter an inconsistent sort result.  The position of "01.0" and/or
"01.2" seems wrong.


$ cat /tmp/test.el
(require 'ls-lisp)
(print (sort (vector "01.0" "10" "010" "01.2")
             (lambda (x y)
               (ls-lisp-version-lessp x y))))
$ emacs -Q --batch -l /tmp/test.el

["01.0" "10" "010" "01.2"]
$
