Gosh, I forgot to filter out the initial Git repository setup!  Fixed in 
the attached script.  Now I only see three warnings in red with the 
current master: the famous https://gitlab.gnome.org/GNOME/gtk/issues/221 , 
two obsolete warnings in cedet/semantic/idle.el , and the (sporadic) 
Python shift/reduce conflict.

Yes indeed, that's it, somehow all computers I see/use have 
hyperthreading, and I concluded a bit too fast that this was always the 
case.  Also fixed in the attached script, which uses /proc/cpuinfo.
