Quote the branch name in "Check out branch" button
In https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22056 the branch name is `#51457-Show-percentage-of-language-detection-on-the-language-bar` thus it's showing this command: ``` shell git fetch git@gitlab.com:johann.sonntagbauer/gitlab-ce.git #51457-Show-percentage-of-language-detection-on-the-language-bar git checkout -b johann.sonntagbauer/gitlab-ce-#51457-Show-percentage-of-language-detection-on-the-language-bar FETCH_HEAD ``` However see that the branch name becomes a comment? So it won't work if we just copy and paste in the terminal. Actual screenshot: ![Screen_Shot_2018-10-04_at_00.00.18](/uploads/e60e31f00fefced5d56b3f2122879661/Screen_Shot_2018-10-04_at_00.00.18.png) We'll need to quote the branch name, or escape special character like that. Note that a branch could be `tmp'"` so this quote can't be dumb.
