I posted after having purged my system of the offending ???? and was 
writing from memory.

I believe there were two source directories
   /home/richard/.local/share/Trash/expunged/73080846/grub2 
problem-2018-02-13
		and
    /root/.local/share/Trash/expunged/73080846/grub2 problem-2018-02-13
or
    /home/root/.local/share/Trash/expunged/73080846/grub2 
problem-2018-02-13

The crud filled result was a "THING/glob/???" at:
    /media/richard/MISC  backups/dev_sda14/home/richard/.local/share
      /Trash/expunged/73080846/grub2 problem-2018-02-13

Agreed ;/
There had been a mess of house keeping done.

What I was trying to document was that
    cp -ax /  /media/richard/MISC-backups/dev_sda14/root
should be have been expected to run to _intended result_.

In reality, there was a *PERVERSE* permutation of initial conditions.

Now can you understand why *I* am fascinated with "corner cases" ;/
