How can I get rid of them rolf> (they look ugly and aare useless) ? Hi Rolf, do you want to get rid of the trailing WS characters? What I usually do on buffers with trailing WS lossage is M-x picture-mode M-x picture-mode-exit This removes trailing WS characters in the buffer. Do you want to get rid of the visual display as _? See * cperl-invalid-face - The result of evaluation of this expression highlights trailing whitespace. Hmmh, M-x customize-variable cperl-invalid-face does not seem to work!
