It appears that, for some reason, dired-actual-switches fails to
be set.  However, I can't make head or tail of the loops
ange-ftp goes through to get the directory listing.

FWIW, this error only occurs when I try and access a directory
whose parent I cannot read.  That is, I only get the error if I
hit the (file-error nil) part of the new definition of
ANGE-FTP-FILE-SYMLINK-P.
