The username should be used for Merge Request
Created by: Shad0w1nk
I really think the username should be use when accepting the merge request as opposed to using the name: https://github.com/gitlabhq/gitlabhq/blob/master/app/models/repository.rb#L500
Gitlab is already converting the user.name from commit to the User.name in the UI based on the User.username. It would only be fair to use User.username during the commit of the merge.
