Still dangling even with 'file:', using (in my case) this:

 pwd
 rm -rf A B C
 mkdir A B C
 (cd A; mkdir X; cd X; git init; echo x>x; git add x; git commit -m xxx;
  git checkout -b y; echo y>y; git add y; git commit -m yyy;
  git checkout master)
 (cd B; git clone file:///home/kroupa/tmp/gittest/A/X; cd X; git branch -a)
 (cd C; git clone file:///home/kroupa/tmp/gittest/B/X; cd X; git branch -a; git fsck --full)

The actual result of pasting this to shell is:

~/tmp/gittest>pwd /home/kroupa/tmp/gittest ~/tmp/gittest>rm -rf A B C ~/tmp/gittest>mkdir A B C ~/tmp/gittest>(cd A; mkdir X; cd X; git init; echo x>x; git add x; git commit -m xxx;

>  git checkout -b y; echo y>y; git add y; git commit -m yyy;
>  git checkout master)
