I am rather against this patch and the corresponding for subfile: these
protocols are not harmful by themselves, they are dangerous if and only
another protocol or format allows untrusted sources to provide arbitrary
URLs. This kind of preemptive blacklisting is bound to fail (new protocols
are added frequently, and they may be more dangerous than just concat or
subfile) and only mitigates a few of the possible attacks.

If people start to care about playlist-based security issues (Reimar used to
warn about it long ago), a cross-protocol solution needs to be found.
