Proposal: accept pull requests on GitHub

[Edward Z. Yang]

Hello Nikita,

Phabricator has a model where you can make all of your comments in a
batch (unsubmitted), and then submit them at once.  TBH, I've never
had a workflow where I didn't want my intermediate comments to be
posted immediately, but it also hasn't been too much of a bother
to make my comments, and then scroll to the bottom and submit.
