A commit message consists of three sections: Header(required), Body(optional)
and Footer(optional).
Header is a single line string which is composed of three parts:
type(required), scope(optional) and subject(required).
<type>(<scope>): <subject>
// An empty line
<body>
// An empty line
<footer>
To avoid automatic line wrapping, always wrap lines of a commit message
to 72 characters.
