This PR was merged into gushphp:master branch.

Discussion
----------

When you create pull request via GitHub interface then it's title default to 1st line of 1st commit message in branch that is used to create pull request.

It would be great if Gush could do the same. Right now I have to retype same commit message again to create PR.
