Fix for skipping last two nodes in processing

[thefourtheye]

It skips the processing of last two nodes. The example itself doesnt work, because of this bug.

bin/swiffer examples/jsControl.tl

doesn't show anything in the console. With this fix, it shows the following

Line p, Column o: Use one of the available special characters: s, n, r, lb, rb
@if is deprecated. Please use @eq, @gt, @lt, etc.

Sorry for the confusion on this one. The reason for using node.length - 2 instead of the full node.length is a dependence on a very recent change to Dust.js, which adds lines and columns as the last two items of each node.

Until a new version of Dust gets pushed to npm, the best thing to do is probably:

1. Clone LinkedIn's fork of Dust.js

$ git clone https://github.com/linkedin/dustjs.git

1. Copy everything in the Dust.js directory into the dustjs-linkedin directory in Swiffer's node_modules directory:

$ cp -R /path/to/dustjs/* /path/to/swiffer/node_modules/dustjs_linkedin/.

1. Try running an example again (from within the swiffer directory:

$ bin/swiffer examples/jsControl.tl

Expected output:

Line 5, Column 1: Use one of the available special characters: s, n, r, lb, rb
Line 6, Column 1: @if is deprecated. Please use @eq, @gt, @lt, etc.

The latest revision of Dust (2.0.1) has been published to npm, so all you need to do now is run npm install.

Perfect. Thanks! :)
