Easily version control a single file under vim

Git was not designed for single-file projects, or managing multiple text files independently within a directory. However, below shell script and accompanying Vim commands work around it by creating a unique bare repository for each file (using a Git command to set a different location for each file's .git directory).

Command-Line Instructions

Copy the following script into a folder in $PATH, say as ~/bin/git1 (or g1) and mark it executable:

#!/usr/bin/env bash

change permissions to be sane or safe inside a $dir by chmod-sane/safe $dir
#!/bin/sh
# Change file permissions to be sane or safe inside a directory $dir by
# chmod-sane/safe $dir
# For example, ~/.gnupg better be safe whereas ~/.cache can be sane.
# Set permissions in a specified directory to a
# standard, reasonable setting where directories are executable and readable by
# all users (755), and files are readable and writable by the owner, and readable
# by others (644). Additionally, files with execute permissions set for any user
