Ensure 'cd gitlab' is done in current directory
For some reason tmux cannot find the gitlab directory without explicitly prepending the current directory.
Was getting support/set-gitlab-upstream: line 5: cd: gitlab: No such file or directory
in return without being explicit about the cwd. This change got it working in tmux — while still working outside of it in bash — for me but if there’s a saner alternative I’m all ears.
