Could you clarify the reason for the first patch? Did you have any test 
failures (on Ubuntu 20.04.1?) with the current test code because of the 
"random" filesystem traversal order? Thanks!

Re: patch 2, I have an idea that would make it a bit simpler and less 
coupled to project.el, but behave the same in the usual cases. Stay tuned.
