// Package config implements encoding and decoding of git config files.
//
// Configuration File
// ------------------
//
// The Git configuration file contains a number of variables that affect
// the Git commands' behavior. The `.git/config` file in each repository
// is used to store the configuration for that repository, and
// `$HOME/.gitconfig` is used to store a per-user configuration as
// fallback values for the `.git/config` file. The file `/etc/gitconfig`
// can be used to store a system-wide default configuration.
//
// The configuration variables are used by both the Git plumbing
// and the porcelains. The variables are divided into sections, wherein
// the fully qualified variable name of the variable itself is the last
// dot-separated segment and the section name is everything before the last
// dot. The variable names are case-insensitive, allow only alphanumeric
// characters and `-`, and must start with an alphabetic character. Some
// variables may appear multiple times; we say then that the variable is
// multivalued.
//
// Syntax
// ~~~~~~
//
// The syntax is fairly flexible and permissive; whitespaces are mostly
// ignored. The '#' and ';' characters begin comments to the end of line,
// blank lines are ignored.
//
// The file consists of sections and variables. A section begins with
// the name of the section in square brackets and continues until the next
// section begins. Section names are case-insensitive. Only alphanumeric
// characters, `-` and `.` are allowed in section names. Each variable
// must belong to some section, which means that there must be a section
// header before the first setting of a variable.
//
// 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"]
//
// --------
//
// Subsection names are case sensitive and can contain any characters except
// newline (doublequote `"` and backslash can be included by escaping them
// as `\"` and `\\`, respectively). Section headers cannot span multiple
// lines. Variables may belong directly to a section or to a given subsection.
// You can have `[section]` if you have `[section "subsection"]`, but you
// don't need to.
//
// There is also a deprecated `[section.subsection]` syntax. With this
// syntax, the subsection name is converted to lower-case and is also
// compared case sensitively. These subsection names follow the same
// restrictions as section names.
//
// All the other lines (and the remainder of the line after the section
// header) are recognized as setting 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.
//
// A line that defines a value can be continued to the next line by
// ending it with a `\`; the backquote and the end-of-line are
// stripped. Leading whitespaces after 'name =', the remainder of the
// line after the first comment character '#' or ';', and trailing
// whitespaces of the line are discarded unless they are enclosed in
// double quotes. Internal whitespaces within the value are retained
// verbatim.
//
// Inside double quotes, double quote `"` and backslash `\` characters
// must be escaped: use `\"` for `"` and `\\` for `\`.
//
// The following escape sequences (beside `\"` and `\\`) are recognized:
// `\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
// and `\b` for backspace (BS). Other char escape sequences (including octal
// escape sequences) are invalid.
//
// Includes
// ~~~~~~~~
//
// You can include one config file from another by setting the special
// `include.path` variable to the name of the file to be included. The
// variable takes a pathname as its value, and is subject to tilde
// expansion.
//
// The included file is expanded immediately, as if its contents had been
// found at the location of the include directive. If the value of the
// `include.path` variable is a relative path, the path is considered to be
// relative to the configuration file in which the include directive was
// found. See below for examples.
//
//
// Example
// ~~~~~~~
//
// # Core variables
// [core]
// ; Don't trust file modes
// filemode = false
//
// # Our diff algorithm
// [diff]
// external = /usr/local/bin/diff-wrapper
// renames = true
//
// [branch "devel"]
// remote = origin
// merge = refs/heads/devel
//
// # Proxy settings
// [core]
// gitProxy="ssh" for "kernel.org"
// gitProxy=default-proxy ; for the rest
//
// [include]
// path = /path/to/foo.inc ; include by absolute path
// path = foo ; expand "foo" relative to the current file
// path = ~/foo ; expand "foo" in your `$HOME` directory
//
