// Section is the representation of a section inside git configuration files.
// Each Section contains Options that are used by both the Git plumbing
// and the porcelains.
// Sections can be further divided into subsections. To begin a subsection
// put its name in double quotes, separated by space from the section name,
// in the section header, like in the example below:
//
// [section "subsection"]
//
// All the other lines (and the remainder of the line after the section header)
// are recognized as option variables, in the form "name = value" (or just name,
// which is a short-hand to say that the variable is the boolean "true").
// The variable names are case-insensitive, allow only alphanumeric characters
// and -, and must start with an alphabetic character:
//
// [section "subsection1"]
// option1 = value1
// option2
// [section "subsection2"]
// option3 = value2
