Doesn’t work with latest Node 11

[strogonoff]

I suspect this has to do with one of dependencies (nodegit?) using old version of promisify-node (looks like a similar issue: askmike/gekko#2150).

% npm -g install css-ast-diff
/usr/local/bin/css-ast-diff -> /usr/local/lib/node_modules/css-ast-diff/bin/css-ast-diff

> nodegit@0.11.9 install /usr/local/lib/node_modules/css-ast-diff/node_modules/nodegit
> node lifecycleScripts/install

/usr/local/lib/node_modules/css-ast-diff/node_modules/promisify-node/utils/args.js:9
  var args = func.toString().match(/function\s.*?\(([^)]*)\)/)[1];
                                                              ^
