Next one has to care for Post-gap: table 555 in mmc5r03c.pdf does not
show any although 6.33.3.19 would prescribe some.
ts B20111: Table 1 of MMC-1 shows two post-gaps. The first matches the
precriptions with SEND CUE SHEET. The second one is riddling.
Both are part of a track and occupy the range of the last index
of the track. Length is 2 seconds for each.
Nobody seems to have ever tested this situation, up to now.
It is banned for now in burn_disc_write().
