into nitpicking mode, so the test-cases reveal if the VCC outputs
anything bogus or suspect.

find out how that can work.

Make min/max values strings, and test-convert them along with the
default value during startup, to see that we can.  At the same time

Add a new feature:

	param.show changed

will only list parameters with non-default values (in short format)

various pointless malloc'ing.

VSB instead.
