Here's an alternative first patch that rolls patch 1+3 into one. I'd
like some feedback on this before I continue hacking on patch 2. While
I don't like that we accept any old broken srt file, especially without
knowing what software made it, I'm not completely opposed to
compromising in this specific case. But I'd rather we didn't, and stuck
to \r, \n and \r\n. What I really don't want is runs of \r being eaten
without being "terminated" by a \n, because this messes up Mac support.
