Thanks. Yes, that sounds better.

I think II) above is not specific of ls-lisp: the same happen with
GNU ls.
With emacs -Q:
(let* ((dir (expand-file-name "src" source-directory))
(default-directory dir))
(dired (list dir "cygw32.c" "alloc.c" "w32xfns.c" "xdisp.c")) ; Wrong aligment.
;; Following just fix the first file, but xdisp.c keeps misaligned.
(dired-goto-file (expand-file-name "cygw32.c"))
(forward-line 0)
(let ((inhibit-read-only t))
(dired-align-file (point) (point-max))))
Note that when i eval the previous form GNU 'ls' is used, and i see misalignment.
I would expect `dired-align-file' fix this problem, but i doesn't.
*) Since this is not specific of `ls-lisp', one alternative fix could
be to run `dired-align-file' at the end of `dired-internal-noselect'
when `dired-directory' is a cons.
**) First, we must fix `dired-lign-file', which is not doing its job
in the snippet above.
