Not sure if it was Mac or phone, and I'm not sure if it was strictly emdash or one of the other seemingingly hundreds of different length dashes, but there was a time at least that -- would be rewritten to it. Also macs have this really really annoying habit of changing the dash when copying and pasting (but not always) so the nunver of times copying a bash command errors because it wasn't a dash, or I've copied a command to WhatsApp and the recipient got an error is enough to make me hate these clever dashes forever
