[vlc-devel] [PATCH] Don't restart playlist after converting current item to node

[bl4]

Playlist is restarted after converting current item to node (for example 
when reading a directory).

Suppose there are 3 files: 1.mp3, 2.mp3, d/3.mp3

When I run vlc like this: `vlc 1.mp3 2.mp3 d`
it plays the items in following order: 1.mp3, 2.mp3, 1.mp3, 2.mp3, d/3.mp3

It's because when the current item is converted to node, it's removed 
from the onelevel playlist but p_playlist->status.p_item is not updated. 
After that, ResetCurrentlyPlaying function is called to set the current 
index. It can't find status.p_item inside status.p_node so it sets the 
index to -1 and the playlist is restarted.

This patch updates p_playlist->status.p_item to point at the previous 
item when converting current item to node so ResetCurrentlyPlaying can 
find it and the index is incremented correctly.
