$GIT_DIR is interpreted by git as an environment variable, pointing at the .git directory. If git_version_gen.sh is run in an environment with an exported GIT_DIR, it will re-export GIT_DIR to point at the fish source directory. This will cause git operations to fail. This could be reproduced as building fish as part of an interactive rebase 'exec' command. git_version_gen.sh would always fail!
