Addresses issue #528

[kenahoo]

I'm not sure what the test failures are about - in my local environment, a huge number of tests fail spectacularly both before & after the patch so I'm not sure if the new code is responsible for it or not.

I'll try to review and figure out what's going on next week.

[kenahoo]

Thanks, appreciated.

Hi @kenahoo -- thanks for your patience. This PR looks good to me, and I think the Travis failures are unrelated.

For contributions to RStudio's open source projects, we do require a contributor license agreement -- would you mind filling that out and sending it to the e-mail indicated in the form?

Once we have that on file I'll be happy to merge this PR. Thanks!

[kenahoo]

@kevinushey Sure, I can do that - I thought I'd done this before, though, any way to check whether I'm already "in the system"?

[kevinushey]

We do maintain a database of signed CLAs, but I didn't see your name in there -- if you have signed one before and it just wasn't added for some reason, I apologize. Would you be willing to file a new one in any case?

[kenahoo]

Yup - just making sure I push it through the right channels at my company, I hope to have it back today or tomorrow.

[kevinushey]

Sounds good -- thanks for your patience.

Hey @kevinushey , I think we probably want to use the https://www.rstudio.com/wp-content/uploads/2014/06/RStudioCorporateContributorAgreement.pdf in this case, since I did this on "company time" while working on some deployment stuff for an internal application, sound correct? Company is NextEra Analytics (formerly known as WindLogics).

[kevinushey]

That sounds correct to me.

[kenahoo]

I've sent the signed agreement document to JJ.

[kevinushey]

Thanks! We've received the CLA; I'll merge this now.
