yes

i agree, but not because the solution is good, just becasue it avoids the mess 
of 2 different ways to store the headers

the packing used for the vorbis headers (as in libavformat/matroska.c) has 
overhead of 
O(n/255) 
while get/put_v borrowed from nut.c would have 
O(log2(n)/7)

so for 128-254 your suggestion would be 1 byte while 2 for get/put_v
for all others get/put_v would be equal or shorter

for 1mb put/get_v would need 3 bytes while your suggestion would need 4113 
bytes
