This removes newlines before and after the messages in
append_todo_help(). This is done to avoid confusions from
translators.

These newlines are now inserted with
`strbuf_add_commented_lines()`. Messages were ended by two newlines
characters, but here we only insert one at a time. This is because
`strbuf_add_commented_lines()` automatically inserts a newline at the
end of the input, and ignore the last from the input.
