You are right, my bad.  When I went to check on what the venv prompt 
looked like after activation, I hadn't run my Linux VM for too long and 
forgot that the activate script needs to be sourced - in Windows it just 
gets run as any other script. I noticed it wasn't marked executable and 
blindly "fixed" that.  Then of course I remembered the script has to be 
sourced  - and forgot to undo the execute flag.
