remove_copymark error

Well, I did notice that that +pal 13 wasn't working, so I ended up tracing why. 

```
remove_copymark[-$#--1]
```

That's the line. Just near the finish of +pal command. I'm not sure what happened, but it's nothing to do with my code as that line is near toward the end, and when I removed it, it works, but with ._c1 at the end.

That being said, I might go with a redesign of the +pal code itself.
