document print-values
Print a list of values.
Takes one argument, the value to print, and prints all the values which
are chained through the next field.  Thus the most recently created values
will be listed first.  The "Contents0-3" field gives the first "int"
of the VALUE_CONTENTS; not the entire contents.
