Thanks, Chet. Still, the original post mentions an anomaly or two that 
supposedly apply to more recent versions (4.4.19 and 5.0.17) and it is 
those that have been bothering me especially. I called them out in my 
original reply.

One example is that gregrwm claims the following outcome for 5.0.17(1) 
in Ubuntu 20.04:-

  $   echo @(?|.?)      #. and .. are included
. .. a .b

Note that '.' is said to be among the pathnames matched. I don't see how 
this can possibly be the case. I'm hoping that it was merely a case of 
making a mistake in the course of performing the tests and assembling 
the results.
