Do not force empty line before indent mode

This was not intended,  only indentation was intended (no pun indented).

Seriously, omitting the newline makes the -i mode more useful as we can
now use syntax like:

    mkusage "topic" \
      --
      "topics:" \
      "${topics[@]}"

That is much less code, especially if the list we wanted to include is
already in array.
