The main problem is that as it works now (at least for me) is that it 
actually deletes everything I have written if there are matches both in 
magics and regular. For example if I try to complete on 'color' when in 
pylab mode then I get a list of 5 matches 2 magics and 3 regular but I 
get to start all over again and type in color again:

In [1]: color
colorbar    colors      %colors     colormaps   %color_info

In [1]: 			<--Empty line

I find it quite annoying to have to retype things in cases like this.

I think it would be nice to get alla matches including magics but not if 
the price is that I loose things I have typed.
