It's worth noting that we'll fix that with the new config system.
Currently we have a hodgepodge of manual settings and magics that do
the extra work needed to flip the option and update other things (like
%colors), but in the future, TConfig (currently in ipython1) will
allow us to always do the right thing, by hooking trait change
listeners into the options structure.

More on that coming later...
