* The "implicit" portion of the IN command.

* palette. The difficulty is that they want to reset it to different things.
*
* The proper way to handle this would be to implement IN as a reset type,
* create a single palette reset routine, and have it do different things
* depending on the nature of the reset.
*
* At the time this comment was written, such a change was larger than could
* be easily accommodated. Hence, a less drastic alternative was employed:
* split the IN command into implicit and explicit portions, and only use the
* latter when the IN command is explicitly invoked.
