Hello John, thanks for this fix for #382.

Are you able to update the relevant values in the withMetadata docs also?

I'd very much prefer not to introduce mocha to dependencies; test dependencies belong in the devDependencies section. If there's a specific platform this doesn't work on, I suggest the use of npm install -g mocha.

Will push later today

Interesting if I have mocha installed locally, all tests pass
When installed globally I get this

1. Input/output Handle Stream to Stream error :
   Uncaught Error: EPERM: operation not permitted, open 'C:\Users\User Name\Documents\OpenSource\Sharp\test\fixtures\output.jpg'
   at Error (native)

Some funny with mocha I believe

Sorry, I think I may have confused things. Please leave mocha where it is, in devDependencies. This PR should not require any changes to package.json.

Thanks for updating the docs. Please can you rebase against upstream/master and squash into a single commit and we can get this into the forthcoming v0.14.0.

Thanks for the changes, looking great. Are you able to squash into a single commit? I notice the commits are from (or at least are linked to) a different Github account - is this intentional?
