Bug: offset=0 offsets text by width of stroke

[plepe]

I found a bug, that an offset by 0 offsets the text by the width of stroke. According to the code, this should be the default when no offset is set.

Example:

Test code:

        var map = L.map('map')
                   .setView([ 50, 15 ], 5)

        for (var i = -3; i <= 3; i++) {
          var line = L.polyline([[ 50 + i, 10 ], [ 50 + i, 21 ]], {
                      weight: 7,
                      color: '#8EE9FF'
                  }).addTo(map);
          line.setText('  offset ' + i, {repeat: true,
                              offset: i,
                              attributes: {fill: '#007DEF',
                                           'font-weight': 'bold',
                                           'font-size': '12'}});
        }
