[Gimp-developer] Level to Curves broke with recent update

[Elle Stone <ellestone ninedegreesbelow com>]

Open an image.

Open the Levels dialog.

Move the sliders as desired.

Choose "Edit these Settings as Curves".

What should happen is the Curves dialog opens up, already with 
appropriate points to duplicate the Levels settings.

What does happen is the Levels settings are applied to the image, then 
the Curves dialog opens up, already with appropriate points to duplicate 
the Levels settings.

So the desired adjustment is already applied once with Levels and ready 
to be applied again with Curves.
