Some comparisons are always false

As these comparisons are always false, the logic cannot be detecting

anything that might have gone wrong.

We mark this as always-false and leave the fix up to upstream.

 Buffer input up to

 set this to anything below the blocksize. Useful when writing tapes

 Concurrent operation. Use a seperate process for outout. This is

 especially useful in combination with the -B option.
