makes console.log display method and line info.

consolefix.js

var methods = ['log', 'warn'], i, len, old;

for (i = 0, len = methods.length; i < len; i++){ 
    old = console[methods[i]];
    
    console[methods[i]] = function() {
        var stack = (new Error()).stack.split(/\n/);
    
        if (stack[0].indexOf('Error') === 0) {stack = stack.slice(1);}
    
        var args = [].slice.apply(arguments).concat([stack[1].trim()]);
    
        return old.apply(console, args);
    };
}
