Log Message:
-----------
Add details of how to disable spurious warning messages about obsolete built-in 
variables. These result from the octave 2.0/2.1 compatability code which is never 
actually executed in octave 2.9. Unfortunately the interpreter doesn't know that.

This fix is not enabled globally by default since it would also suppress genuine 
warnings for users upgrading code to octave 2.9. It cannot be done individually within 
a file as the warning must be disabled before the interpreter parses the file. Urgh...

+    Note: As a result of the compatibilty code for octave 2.1 and lower the
+    octave bindings will generate spurious warnings about obsolete built-in
