Run: merge,
GitExtension: true,
Usage: "merge <PULLREQ-URL>",
Long: `Merge a pull request locally with a message like the GitHub Merge Button.
This creates a local merge commit in the current branch, but does not actually
change the state of the pull request. However, the pull request will get
auto-closed and marked as "merged" as soon as the newly created merge commit is
pushed to the default branch of the remote repository.
To merge a pull request remotely, use ''hub pr merge''.
## Examples:
$ hub merge https://github.com/jingweno/gh/pull/73
> git fetch origin refs/pull/73/head
> git merge FETCH_HEAD --no-ff -m "Merge pull request #73 from jingweno/feature..."
