Ignoring the fill value of masked array feels like a bug to me...

Where I cared was when trying to do a filled line plot in matplotlib and 
the nans, rather than being omitted, were being shown on the y-axis at 
999999, totally wrecking the plot.

I'll buy your argument *iff* the masked arrays used the fill value from 
the parent ma.
