SCI mutant output highlights the wrong line

[phihos]

Example:

   - [#  33] SCIP tri.struct._pystruct:60 : 
--------------------------------------------------------------------------------
 56:             del self[item]
 57:         except KeyError:
 58:             object.__delattr__(self, item)
 59:     
~60:     def copy(self):
 61:         super().copy()
 62:         return type(self)(self)
 63: 
 64: Struct.__module__ = 'tri.struct'

Line 61 should be marked instead, because this line was actually inserted.
