description:
Add a knob to control whether -V fully expands a plain variable by default.
The default retains the traditional NetBSD behavior, but the knob
can be set so that FreeBSD can retain their expected behavior.
This is a compromise to be sure.

Add a debug flag -dV to override the above, so that regardless of
the knob setting, the raw value of a variable can be easily seen.
