--------------------------------------------------------------------

I'm playing shell games. :D

--dockermode is a standalone option that says "hey, we were invoked underneath 
docker, don't spawn another one" TESTPATCHMODE has all of the user passed 
parameters.  We then append --basedir, etc to *override* the values in 
TESTPATCHMODE.

So this code is adding --dockermode to the parameter list.  If you want, I can 
move --dockermode to be after TESTPATCHMODE if it makes it cleaner.  Or maybe 
just a comment here, warning of the black magic in the works.
