Short description of error
When using the knife intersection with default 'separate' option, the intersection is correct, but done 4 times.
Exact steps for others to reproduce the error
Open attached file with default cube an a plane, hit spacebar in 3D view, call intersect (knife), you have 16 created and selected verts although only 4 are needed to draw the square that is the intersection.
The selection state should also reflect the 'separate' option by being really separated from the original meshes. If you hit G after intersection, the cube and the plane are deformed.
Expected behavior: only one filled square should be created and selected. This square should be separated from the original meshes.
bug intersect knife.blend
Note that when separate is unchecked, the duplication problem is not happening, but the newly created verts are not selected anymore.
Excpected behavior in this case: newly created verts are selected like with other operators.
Changed status to: 'Open'

The newly created edges & vertices should be selected, otherwise this is working as intended regarding the geometry output.
"Separate" means intersected surfaces aren't attached to each other.
