Turns out there was a *YUCKY* choice for a default setting.
In the default profile for mate-terminal there is a choice titled
   "Run command as a login shell".
The option is *not* enabled.

That makes the choice "given"(sic) by Caja of
   "Run in terminal"
and
   "Run"
moot.

I consider this a Debian, not Upstream, bug as each distro should be 
responsible for choosing their defaults.
