I might be performing bike shedding here, but wouldn't it be better to
replace those two with "--", as explained in
https://en.wikipedia.org/wiki/Dash#Approximating_the_em_dash_with_two_or_three_hyphens

For EM DASH there seems to be even "---", but I'd say that is a bit too
much.

Or do you fear the extra work as some lines then might break the
80-character limit then?

Ciao, Thorsten
