I had a similar question about supplying a newLine option to the JS concatenation pipeline. It’s slightly different because the concat pipline is passed a filename argument. But would this be the way to go…?

Original:

.pipe($.concat, filename)

Modified:

.pipe(function(filename) {
      return $.concat(filename, {newLine: ';'});
    }, filename)
