Subject: Support "newstyle" Youtube playlist IDs.
X-Git-Url: http://git.jankratochvil.net/?p=youtube-dl.git;a=commitdiff_plain;h=7125a7ca8b5e5228a8199cb95779f83fd3ee05e2

Support "newstyle" Youtube playlist IDs.

Many playlists reported by Youtube now have the form like in:

    http://www.youtube.com/playlist?list=PL520044A3524F5E5D

where `PL` is prefixed to what youtube-dl used to use as playlist IDs. So,
while matching it, we adapt the regular expression so as to discard the `PL`
and only get the `520044A3524F5E5D` in the case of the playlist of the
example.
