>Description:
When multiple commands are given to burncd (for example, one data command
and one fixate command), an error in execution of one command does not
prevent the execution of the next.

Because of this, I ended up with an empty but fixated CD-R :)

>How-To-Repeat:
A command line like the following:
	burncd -f /dev/acd0 data main.iso fixate
issued in a situation where the drive is not completely ready, may result
in a situation where the data-part fails, after which the fixate is attempted,
which succeeds.

>Fix:
Abort when the writing of a data-track fails at 0 bytes.
