I have revised and applied the patch in trunk (r10844). I've also updated the exist test suite entry for this to test exclusion from the autoscaling range (r10843).
Note that the patch does *not* cause nodata values to be transparent - it only ensures they are excluded from the autoscale range calculation. I have updated the debug message accordingly.
There were also some problems with the way the exclusion happened which I have adjusted for.
