Thanks.

We can always improve this later.
Unfortunately this change breaks test 107.
That's because of passing echo_style to list2string(). It doesn't work
to use the inverse of echo_style to decide to restore the copyID. We
need a separate argument for that. Since I wanted to see if that
actually works I already made the change.
test86 and test87 also fail, but it looks like that's because of the
improvement. Thus I'll adjust the .ok files.
