I'd say it had enough info, but too much for what I needed.  I ended
up finding the answer in oggenc/flac.c: it's "\177FLAC" not "fLaC" as
ogginfo claimed.

Is this right, Josh?  While my patched ogginfo now detects Ogg FLAC
properly, I'm not sure if this is the correct method.  ogginfo only
checks for magic and packet size.
