Items 1, 2, and 4 don't solve the stated problem. They result in only CR on the ends of lines (not in only LF on the ends of lines).

Also, your not mentioning "\r" in item 1 makes me think that you may have been confused (like so many) by the '"\n" is logical newline' idea that I find horrid. See Re^4: Line Feeds (rumor control) for more on that.
