Mistake Copying from History Screen

[Tim Wessman]

Its actually not anything in the copy code. Rather, its in the printing of the result. Turn off the 2D stuff and you'll see it still happens.

The 2D code is smart enough to recognize 1+i as a complex and keep it grouped which is why the answer looks correct, but by that time the cas has evaluated and the parens have already been stripped. So when you copy it back x^1+i is actually correctly being interpreted.
