Input audio track 0:1 is copied into the output file.

Note that if you specify -map 0 (to copy all streams), all
output audio tracks except the first one will be silent
(because that is useful for - imo - typical - usecases).
This is probably trivial to fix but I am still searching
for somebody to help testing.

Is it possible to manually (through commandline args) tell it to copy all streams across without the (apparently bugged) -map 0 option?
