lisp/ChangeLog addition:

checking macros.

* lib-complete.el (lib-complete:get-completion-table): Changed to
a label.
* lib-complete.el (read-library-internal): Include labels.
* lib-complete.el (lib-complete:cache-completions): Changed to a
label.
* minibuf.el (read-buffer): Use #'set-difference, don't reinvent it.

repeating a lambda expression.
* packages.el (package-get-key):
