In the shell create a new file:
$ touch ~/2010-02-18\ foo
Then in Emacs:
C-x d ~ RET
and move down to the line file you just created. Only the "foo" portion
is recognized as belonging to the file name. Trying to visit the file
with RET then gives:
dired-get-file-for-visit: File no longer exists; type `g' to update
dired buffer

This works fine for me in GNU/Linux with `emacs -Q', in Emacs 22.3,
23.1, and the current trunk. Maybe this is Mac-specific? Seems odd.

I think it depends on whether your `ls' supports --dired.

Indeed it fails if one sets dired-use-ls-dired to nil.
That variable is initialized in a funny way, via
(string-match "gnu" system-configuration)
I guess (?) many Mac users do indeed have access to GNU ls, despite
not having "gnu" in their `system-configuration'.
It also doesn't really seem to be documented anywhere that dired will
perform less well if the underlying ls does not support --dired.

Speaking of which, is there any particular reason why dired still uses
an external program? If it's because `ls-lisp' is too slow, wouldn't it
be rather easy to, say, extend `directory-files' to return a list of
stat structures instead?

I don't think it's slow on a Posix system, where the `stat' function
is highly optimized and very fast. I think the main reasons are
(a) inertia, and (b) ls-lisp doesn't support all of the switches
available with GNU `ls'.

On Windows it is useful to be able to run Cygwin ls as a program
to see Cygwin's symlinks and permissions.

There should be no problem to support Cygwin symlinks in native w32
code that implements `stat'. Patches welcome.

BTW, the actual problem that triggered this report almost certainly does
not exist anymore, since dired.el now tests "properly" for --dired
support, so it should be found on a Mac. Also the relevance of --dired
is now mentioned in the manual, plus dired gives a message the first
time it is used if --dired is not found to be supported.
I'm inclined to merge this with #9039 and hence close it.

FWIW, I don't mind. I just answered Lars's question about ls-lisp.
