I am totally with Gaff and zombie. I want to see those little flaws, they were a product of where special effects were at during the time the films were made. I want to see the film in its historic context as close to the way the original audience saw it as possible.

To me, if you are going to polish up the special effects with modern technology, why not add some CG explosions, or add in some extra ships via CG. While we are in the process of covering up old special effects, why not add other elements that were not part of the film before, things the film maker wanted to have but couldn't? Why not add windows to the walls of Bespin? What is the big deal with replacing the midgets in THX1138 with CG creatures? I really can't honestly say the white walls or the midgets were better than what they were replaced with, in fact, I'd have to agree the changes are a definite improvement in those instances... but they are out of place.

It is like adding power windows to your 1967 Ford Mustang. Power windows are a definite improvement over cranks any day, but you've just entirely missed the point of owning a vintage car.
