Re: dired-move-to-filename-regexp and Chinese (was: dired-do-toggle)

    But obviously, when we use the ls-lisp functions tinstead
    of the `ls' executable, we can put text-properties so that
    the filename can be found unambiguously without any regexp
    or guessing or anything (including filenames
    like "foo -> bar" or filenames with \n in their names).

This is right.  If ls-lisp can be as general and as fast as
running ls, or nearly so, then it is better for this reason.

As for using the --dired option, the main difficulty is that
we need to handle systems which don't support this option.
If there is a good way to use --dired when it is available
and cope when it is not, that could be a good approach.
