58 On systems such as MS-DOS and MS-Windows, which use `ls' emulation in Lisp,

93 Set this to t if `ls' (or whatever program is specified by
94 `insert-directory-program') with `-lF' marks the symbolic link
95 itself with a trailing @ (usually the case under Ultrix).
97 Example: if `ln -s foo bar; ls -F bar' gives `bar -> foo', set it to
98 nil (the default), if it gives `bar@ -> foo', set it to t.
100 Dired checks if there is really a @ appended. Thus, if you have a
101 marking `ls' program on one host and a non-marking on another host, and
102 don't care about symbolic links which really end in a @, you can

3793 Dired remembers switches specified with a prefix arg, so that reverting
3794 the buffer will not reset them. However, using `dired-undo' to re-insert
3795 or delete subdirectories can bypass this machinery. Hence, you sometimes
3796 may have to reset some subdirectory switches after a `dired-undo'.
3797 You can reset all subdirectory switches to the default using
