Module exporter re-exports projections it has imported

[erikd]

With a simple module that defines a new projection on Data.List like this:

module Foo

project List where
	count = length

the exporter (src/Module/Exporter.hs) for this exports the following projections for module Foo:

project Data.List.List %rDK125 where
{
        x = project_List_x;
        xs = project_List_xs;
        ref_x = project_List_ref_x;
        ref_xs = project_List_ref_xs;
        count = project_List_count;
}

where the first 4 are projections already defined in Data.List. Only the last projection (count) should actually be exported from this module.

Trac is annoying sometimes.

Deleting duplicate ticket.
