Oh, I see, so the "4 times more work per char" is actually not compensated
by the "4 times fewer chars" since these are not displayed anyway.
So it seems to be a plain and simple algorithmic "bug" (linear rather than
constant time complexity), which has been around for a long time already.
Given this, I agree that it doesn't have to be fixed before the release
(tho of course if someone can come up with a quick fix, that's great).
