[vlc-devel] [PATCH] lua/intf/cli: make info command more versatile

[Filip Roséen]

Prior to this patch, the "info"-command could only be used to query
information related to the currently playing entity. These changes
allow the user to get information about other entities in the
playlist, based on the playlist-id.

fixes #17549
