Thank you for your contribution! The hub browse command is already a bit messy in terms of its features, so I've decided not to expand its functionality any more.

Since latest master, you can use hub pr show to open the pull request for the current branch: #2141

hub pull-request show do not open in browser.
I want to set reviewers.

@ncaq:

1. Update to the latest version of hub;
2. Run hub pr show while on the branch associated with your pull request!

It should work. If it doesn't, please open an issue to report a bug and include as much information as you can.

I use hub 2.11.1 on Gentoo.
Maybe it updated soon. I wait.
Thank you.
