Trying to define a sector in Belgian Lambert (1972 or 2008) projections, 
I see the following oddity (linked to the above ?): Using EPSG codes, I 
do get prompted with a choice for either no transformation or one choice 
of transform parameters, but even when I chose "Do not apply any datum 
transformations" I get a sector with the towgs84 parameter defined for 
transformation.

The same happens when I try to define these projections manually by 
choosing in a list.

When I enter the proj4 string without the towgs84 parameter it works as 
expected, i.e. no towgs84 defined.
