Not Plotting Vertical Assymptotes

Anyone have any idea how to stop Plot putting a (near) vertical line at
x=2 in the command:

      Plot[1/(1-x),{x,0,2}]

ie. detect that the function 1/(1-x) has a singularity at x=2 and do
something about it. This is analagous to numerically integrating over a
(integrable) singularity, where the following remedy works:

      NIntegrate[1/Abs[Sqrt[x-1]]^2,{x,0,1,2}]

But in this case it doesn't work. Decreasing MaxBend works a bit but the
line is still there.

(I am really interested in drawing paths in the plane using ParmetricPlot)

Any ideas or comments
