source representation of getter and setter methods is wrong

jjs> function f(){ return Object.getOwnPropertyDescriptor({set ":"(a){}}, ":").set }f()

Expected: include leading `"` in function source representation
Actual: returns `:"(a){}`

Even without funny names, simple getter, setter source representation leaves "set" and "get" - would be better to uniformly include "get" or "set" in source representation.
