to force internal units to be used; this usage is now deprecated
and needed to be changed to the "units" command. Also: Fixed a
separate issue with getting both "view bbox" and "view get" to
return values in the currently selected units. Also: Fixed an
issue with "property" when setting a property to a list passed as
a single value (e.g., "property FIXED_BBOX [box values]"), which
needed to null the string after each value.
