* bug#18836: 25.0.50; `insert-directory' barfs on nonexistent file, but not for `ls-lisp-insert-directory'

It seems that at least on some platforms (e.g. GNU/Linux), if you give
an explicit list of files and dirs to `dired', to list (which you do by
passing a cons as argument DIRNAME), the command fails with an error:
(file-error "Reading directory"
"no such file or directory"
"/usr/foo/no-such-file.txt")
No such error is raised on platforms that use `ls-lisp'.
This non-`ls-lisp' behavior is not as friendly as it could be, and not
as friendly as the `ls-lisp-insert-directory' behavior, which simply
displays a message and then calls `ding':
(message "%s: doesn't exist or is inaccessible" file)
Would it be possible to make vanilla `insert-directory' more tolerant,
i.e., make it act like `ls-lisp-insert-directory', in this respect?
Failing to access a single file should not prevent listing the others,
if this can be handled properly. But maybe it's not feasible; dunno.
[FWIW, I would even prefer to see the file or dir listed in the Dired
buffer, even if it does not (yet) exist. Let user attempts to actually
access it raise an error, and let no error be raised if the file is
created after creating the Dired buffer but before the user tries to
access the file.]

I have no opinion on that, but: What on Earth is that function (and all
its adjacent functions) doing in files.el?
(insert-directory "." "-l")
=>
drwxrwxr-x 22 larsi larsi 4096 april 30 16:49 .
This doesn't seem like a very ... useful general function.

Where else would you like them to be?

Then how come dired.el calls it?

Dired isn't preloaded.

But does anything other than dired use it? I see that other packages
(like ange-ftp) instrument it... it that the reason it's in files.el?

Yes. Also, ls-lisp.

This has changed between reporting this bug and now -- both now signal
errors currently, so I'm closing this bug report.

Thanks.
I've filed bug #53524 for the additional improvement.
Users should be able to create the listing, with the
missing file/dir. An error should be raised only if
and when you try to visit that file/dir.
