fixed: spec: failure when Git config is set to `diff.noprefix=true`
requested to merge ashumkin/gitlab-ce:spec-failure-when-git-config-diff-noprefix-eq-true into master
What does this MR do?
Fixes tests failure when they are run in a enviroment where git config --global diff.noprofix true
Why was this MR needed?
Tests may fail on a stable master branch. Such a failure is difficult to investigate because one can even don't remember he has Git configured with diff.noprefix=true.
