%(playlist_index)s stopped working

[suomiy]

NA is written to the output filename, instead of playlist index. In the earlier version (I don't know, which one), it worked fine with the exact setup. Has something changed, I am not aware of?

for example:

youtube-dl --playlist-start 5 --playlist-end 5 http://www.youtube.com/playlist?list=PL-vU1BvDAMAZJm5nWjbRD0h6NtOkFq5Q4 --verbose

[debug] System config: ['-o', '%(playlist_index)s_%(title)s.%(ext)s']

It's the same as #840, it has been fixed but it hasn't been released. Maybe it's time to update a new version: @phihag?
