Weird. The line in question is this:

  test "#!" != "$(head -c 2 < "$symlink_target")"

Is there some problem with running "head" on your system? If it were
head failing to open git-instaweb, it would look more like:

  $ head -c 2 /etc/shadow
  head: cannot open `/etc/shadow' for reading: Permission denied
