buf[i] not working sometimes

[andrewrk]

Causing zlib-browserify to be broken: brianloveswords/zlib-browserify#6

To produce the issue:

1. Clone this gist
2. browserify test.js >out.js
3. Copy out.js into jsbeautifier.org and then paste back into out.js
4. Add a debugger statement like this:

                        debugger
                        a.C = l[k++];
                        a.D = l[k++];
                        (31 !== a.C || 139 !== a.D) && m(Error("invalid file signature:", a.C, a.D));

1. run in the browser

You will notice that l is a Buffer and l[0] is yielding undefined when it should yield 31. Note also that l.parent[0] works.

@substack might be interested to see this.

I've found that an implementation of a streaming Boyer-Moore-Horspool search streamsearch breaks because of this. Seems pretty egregious as it's a break from the Node API.

@terinjokes for what it's worth, I think I got around the issue by using https://github.com/chrisdickinson/bops

but even then there was an issue I had to work around: chrisdickinson/bops#7

This actually looks fixed in HEAD, but hasn't been pulled into a newer version of insert-module-globals.
