Ok, this works now, thanks!

Glenn, if you have some more time...  Now that dired respects the -b
option, I wonder if it would be possible to get file names with newline
characters working?

I.e., set dired-listing-switches to "-abl".  Create a directory "a
b" somewhere.  It gets shown as "a\nb" as expected.  But if I try to
visit it from dired, I get this error:

Would be cool if it worked.
