Hi!
I have had this changed version in my fork for a long while but somehow never tried to make a pull request out of it. As far as I can tell it is equivalent to the current version but simpler to understand at least for me and has worked correctly for me.

I saw the recent activity on the package and thought it might be a good opportunity to get rid of my own version. Please let me know what you think.

Looks ok. In my original code I tried to not call cons and create garbage unless I had to, which is why I modified the prefix maps in-place.
Do you think we could do it with cl-loop instead? That would be peak readability. After writing this package I found out that cl-loop has in-ref to help modify lists in-place.

I did it with cl-loop and it is even shorter and doesn't do the consing and works for some quick testing I have done.
