commit 314e0b516ddd87f0ed17f6cedce728fe5a894614

    Missing enclosing parenthesis on the if statement. Also drop the cd against GIT_DIR, that is the working 
directory by default. The setfacls calls are staying where they are now as any eventual pre-receive hook 
rejected commit writes an object on disk. The respective commit is marked as dangling and will be purged by 
git gc (ran on gitlab.g.o via the git user)
