Show line terminators

I sometimes have to work with files where both "\r\n" and "\n" are used and have different semantics (e.g. a datafeed containing market data where they are used as record and field group separator. I don't know who's brilliant idea that was...). I also need this feature to debug generated MIME-Emails, where e.g. Outlook and Thunderbird are very sensitive to which line terminators are used in header and body text. HTTP-requests or responses are another scenario where this could be useful.

For now, I have to switch back to Notepad++ whenever I encounter one of these files. I'd really love to only use Sublimetext.
