I'm not sure why this is happening.  I've extracted the commands from
the gnuplot stream that generate the colorbar and attached them
below.  If you can tell me what we should be sending to gnuplot to get
the correct behavior, I might be able to fix Octave to generate the
correct set of commands.

This feature is not implemented yet.  You can use a cell array
of strings for the labels instead, or perhaps someone will implement
the split feature in the code that handles the tick labels.
