I have a subtitle file that Notepad++ detects as having Unix style line endings, when in fact, it doesn't. At all. To test this, I did the following:

1. Open file
2. Observe Notepad++ claims Unix style line endings
3. Replace \r with nothing
4. Save with different name
5. Reopen new file
6. EOL conversion to Dos/Windows style
7. Save
8. Reopen new file
9. Observe Notepad++ claims Unix style line endings

If you diff the original file with the new one, you'll find that they're identical! In fact, a regex search (wrap-around, "." flag off) on the file for [^\r]\n returns nothing.

Here's the file in question: Inception (2010).BRRip.English.srt
