config object transforms are run twice

[simonzack]

Doing the following will run transforms twice, no matter what the transform is:

var bundler = browserify('file.js', {
    transform: [to5ify]
});

using .transform instead works.

Seeing this as well. Here's a more complete repro:

var browserify = require('browserify');
var through = require('through');

function transform1() {
  console.log('this log line appears once');
  return through();
};

function transform2() {
  console.log('this log line appears twice');
  return through();
};

browserify('./blank.js', {
  transform: [transform2]
})
.transform(transform1)
.bundle();

All fixed in 9.0.2.
