> * lisp/emacs-lisp/pcase.el (pcase-dolist): Use `pcase' rather than
> `pcase-let*' to match the list elements.  Update the docstring,

That changes its behavior.  It *will* break code.
This is basically not the same macro any more.  Instead of being a macro
that iterates over all the elements of the list, it becomes a macro
which iterates only over the matching elements.
