While working on a show with minor clipping I was using the pencil tool to reshape the peaks where they flat-lined. After a few I was able to refine a method that produces good, consistent results. What I found works best (for accuracy, not speed) is to select one of the sample points (click and hold), and move your mouse straight up or down to place it; then, move your mouse straight left or right to the next sample and shift it straight up or down. An example of your movement would be up-right-up-right-down-right-down-right, or down-right-down-right-up-right-up-right if you were working left to right on the wave. Don't move your mouse in a curved motion. Many of you may have figured this out, but it really simplified my work and I thought it was worth sharing. Using a curved motion works, but can be a little more unpredictable. If you have a lot of clipping the curved method is probably best for speeds sake. With fewer clips this method provides more accuracy when manipulating the shape, in my opinion.
I've attached screen-shots of clipping on my file and how it turned out after using the above method.

FWIW, I don't even try to provide a smooth wav form like you've done any long. I used to try, but I couldn't hear any difference when I did.
What I do instead, in a situation like you picture above:
1. split the tracks
2. select the "brickwalled" points
3. effect > amplify > -(0.02)
That more or less uniformly reduces the sampled points. Sometimes it's necessary to repeat, or change the size of the selection and do more on certain points.
At this point, I only use the pencil tool when I've got 2-3 wav points crushed. Anything much more than that I use the method I describe above. At first it's hard to remember to recreate the stereo track (was for me, anyway), but you figure it out pretty quickly.
YMMV, of course.

again, I recommend the clip peak restoration plug in in Cool Edit. Works great!
