Bad drawing of TGraphErrors with option e4

Hello,

In my working example, option e4 gives bad ribbon size for the last point. e3 works fine. Please just use

TGraphErrors *g = new TGraphErrors("tmp.txt")
g->Draw("Ae4")
new TCanvas()
g->Draw("Ae3")

and compare.
tmp.txt (566 Bytes)

Thanks, I have not read carefully enough.
