Re: dired-move-to-filename-regexp

[Richard Stallman]

    I thought RMS had recently implemented support for GNU "ls -lD" in CVS
    Emacs.  That should solve the problem in general when GNU "ls" is
    being used, since "ls -lD" exactly identifies where each file name is.
    The problems you're running into would then occur only with non-GNU
    "ls", for which the obvious solution is to install GNU "ls".

Yes, the latest Dired code knows how to use --dired.
However, it does this only on the GNU system:

  (defvar dired-use-ls-dired (not (not (string-match "gnu" 
system-configuration)))

If there is a reliable, trouble-free and quick way to check
whether the ls program supports --dired, that could be used instead.
