They didn't write '/s' though, which is why I mentioned it - took me a minute to understand 'dash s' so thought the commenter I replied to might not have.
(Perhaps '/' is called a 'dash' or something similar in other languages, but it's an 'oblique' or 'slash' usually in English. To lend weight to that theory, I believe 'oblique' comes from it being the oblique/italic form of a dash - so other Romance languages may well give it the same or very similar name to that for '–'.)
