Features:
- Add support for hub pr list --state=merged
- Add base/head/merge commit SHA and merged date information to hub pr list --format=FORMAT
- Un-deprecate converting issues to pull requests with hub pull-request -i <issue>
Fixes:
- Improve detecting default hub pull-request base branch name
- Avoid the Aborted: the origin remote doesn't point to a GitHub repository error by allowing other git remotes as fallback
- Improve hub create dealing with an existing "origin" remote
- Don't choke on literal % output characters when using --format=FORMAT
- Replace deprecated Dial with DialContext
