Olliverschinagl/gitlab ce clarify master branch name

See merge request gitlab-org/gitlab-ce!25965

The 'master' branch name is confusing as it indicates some special branch name,
where it is actually just a 'ref'. 'branches' _is_ a special name as it
indicates 'all' branches.

Lets clarify the example a little to indicate this.
