[1.8.x] Used full variable names instead of abbreviation in examples

The ``ngettext`` function provides an interface to pluralize words and

phrases::

    var object_cnt = 1 // or 0, or 2, or 3, ...

    var object_count = 1 // or 0, or 2, or 3, ...

    s = ngettext('literal for the singular case',

            'literal for the plural case', object_cnt);

            'literal for the plural case', object_count);
