Well, I'm of two minds here, which so far kept me from responding: On one
hand an option that's useful to someone is probably a good thing. Otoh an
option to control a single newline character seems a little too fine
grained to me. Plus I'm a little concerned of burning a short option for
this (niche?) issue. Since you say it's specifically an issue with -i,
would it be an option to add a long-only option providing the intended
variant of behavior, i.e. combining what would (aiui) be "-i -n" with the
current proposal?
