I gave it a try, see appended patch. There's a new user option
`dired-highlight-symlinks'. If non-nil (the default), symlinks are
highlighted the same way as now. With a nil value, they aren't.
You can switch this option on and off globally. However, it would be
better to do this host-wise. For this, we have connection-local
variables. The following code snippet in your ".emacs" switches the
option off for the remote host "remotehost".
--8<---------------cut here---------------start------------->8---
(connection-local-set-profile-variables
'my-dired-profile
'((dired-highlight-symlinks . nil)))
(connection-local-set-profiles
'(:application tramp :machine "remotehost")
'my-dired-profile)

Comments?
Best regards, Michael.
