Controlling exposure of bundled modules

[jmm]

I'm trying to make sense of how to control exposure of modules in a bundle and finding the documentation and behavior difficult to follow.

Given browserify 7.0.3 or 8.0.3 and this directory structure:

- somedir
    bundle.js
    - src
        a.js
        b.js
        c.js

#1)

Is this situation supposed to break the bundle? (does for me):

// src/a.js
require('./b');

// bundle.js
browserify('./src/a')
  .require('./src/b')

Result (when bundle loaded in browser):

Uncaught Error: Cannot find module './b'

#2)

Is this situation supposed to happen?:

// src/b.js
module.exports = "This is b.js";

browserify('./src/a')
  .require('./src/c')

<script src="bundle.js"></script>

<script>
// Logs "This is b.js"
console.log(require(2));
</script>

I've uncovered the source of problem # 1. Details to follow.

In case it's not clear, the details to follow were in #1059.
