Re: dired-move-to-filename-regexp

[Richard Stallman]

    Another solution is to assume that the current buffer and the one new line
    have used the same ls options and contain the same number of space-separated
    fields.  Based on this, you can add spaces so as to align the fields in the
    new line to the field of the other lines.

That would be rather unreliable, since it would need to figure out the
number of spaces between fields in both the new output and the old
buffer.  The gains that we got from --dired would be lost.
I won't accept this approach.
