I found this old thread.  Could it make sense to have a minor mode that
puts the `invisible' text property on all lines without process-mark?

I have in mind a use case different from Michael who started this thread:

Often I deal with threads that evolve (magically) such that they become
recognized as multiple threads.  In such a case the process-mark can
help to "collect" all threads on a topic.  Or are there better solutions
for this?
