govobj of "rather than"

[jakpra]

"they seemed more interested~in helping me find the right car rather_then just make_ a _sale" (245160.4)

"rather then" has gov "make" and obj null, but in fact "make" should be the obj (and maybe "helping" should be the gov). In UD, "rather" is a cc of "make", so I can see where this comes from, but it would be nice to have govobj.py handle this.
