Subject: 23.1.92; Dired shows wrongly whole directory contents
Date: Tue, 09 Feb 2010 13:42:04 +0100

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
According to the doc, dired shall show single file entries when called
with a list of file names. If a file name is a directory, this works OK
with remote directory names. But with local directory names, it shows
the whole directory contents, which is wrong. Example:

--8<---------------cut here---------------start------------->8---
(dired
 '("foo"
   "~/"
   "/ftp:anonymous <at> alpha.gnu.org:/gnu/emacs/pretest/windows"))
--8<---------------cut here---------------end--------------->8---

results in

--8<---------------cut here---------------start------------->8---
  /home/albinus/lisp:

But I would have expected

The following patch ought to solve this:

The doc seems ambiguous to me, and it is not clear to me what is the
better behavior.  Do you have an argument for why displaying just the
directory name is better?

But the present behavior has been around since at least Emacs 22, so I
don't think we should make this change right now in any case.

Have you tried the example I gave in the bug report? There is definitely
an error, if default-directory points to "~/somewhere/else", and you
apply

  (dired '("foo" "~/"))

You will see the relative file names listed from "~/", but if you click
on a file name, you cannot open, because default-directory is still
"~/somewhere/else".

My proposed change was influenced by the comment in front of
insert-directory:

;; insert-directory
;; - must insert _exactly_one_line_ describing FILE if WILDCARD and
;;   FULL-DIRECTORY-P is nil.
;;   The single line of output must display FILE's name as it was
;;   given, namely, an absolute path name.

It was also in Emacs 21.3 (Drew Adams has tested). But it is still an error.

Best regards, Michael.

Please apply Michael's patch.

When `dired' is passed a cons arg (a list of file or directory names), it should
show a Dired buffer with only those names. A directory name should be inserted
as a single line - the directory contents should *not* be inserted.

I confirm that this works correctly on Windows (e.g. 23.1 and 23-1-91 pretest),
but it works incorrectly on Linux with Emacs 21.3.1. (I don't have access to
other Emacs versions on Linux.)

I see; this is indeed a problem, so I guess we can risk committing the
patch.  Please do so, thanks.
