  After zooming and unzooming on a plot containning several TF1 drawn with
  the option SAME, the functions might be truncated. This problem was
  visible with the following macro:

  TF1* f[6];
  double fg(double *x, double *p) {return sin((*p)*(*x));}
  void test_zoom() {
    for (int i=0;i<6;++i) {
      f[i]=new TF1(Form("f%d",i),fg, 0,2, 1);
      f[i]->SetParameter(0,i+1);
      f[i]->SetLineColor(i+1);
      f[i]->Draw(i?"same":"");
    }
    f[0]->GetXaxis()->SetRangeUser(.1,.3);
    gPad->Update();
    f[0]->GetXaxis()->UnZoom();
    gPad->Modified();
  }

- Fix coding conventions and remove training blanks.
