* When running "make test" in the root directory of this codebase,
an error will occur as this shell script requires a repo to be
initialized before it can properly execute.
This was done in the past, but at some point, it was removed.
This adds the feature back, tests if we are in a git directory
by using a built-in git command, and only performs this action
if a git repo doesn't already exist. All actions are sent to
/dev/null so the testing should look opaque to the end user.
Note that tests will still fail if a user is missing a required
utility to perform the functionality of git-quick-stats.
* Fixed a typo in the man page
Fixes#162
