+	Pathspec is passed in `<file>` instead of commandline args. If
+	`<file>` is exactly `-` then standard input is used. Pathspec
+	elements are separated by LF or CR/LF. Pathspec elements can be
+	quoted as explained for the configuration variable `core.quotePath`

+--pathspec-file-nul::
+	Only meaningful with `--pathspec-from-file`. Pathspec elements are

 --untracked-files[=<mode>]::
 	Show untracked files.

 The mode parameter is optional (defaults to 'all'), and is used to
 specify the handling of untracked files; when -u is not used, the
 default is 'normal', i.e. show untracked files and directories.

 The possible options are:
-+
+
 	- 'no'     - Show no untracked files
 	- 'normal' - Shows untracked files and directories
 	- 'all'    - Also shows individual files in untracked directories.

 The default can be changed using the status.showUntrackedFiles
 configuration variable documented in linkgit:git-config[1].

+COMMIT INFORMATION
+------------------
+
+Author and committer information is taken from the following environment
+variables, if set:
+
+	GIT_AUTHOR_NAME
+	GIT_AUTHOR_EMAIL
+	GIT_AUTHOR_DATE
+	GIT_COMMITTER_NAME
+	GIT_COMMITTER_EMAIL
+	GIT_COMMITTER_DATE
+
+(nb "<", ">" and "\n"s are stripped)
+
+The author and committer names are by convention some form of a personal name
+(that is, the name by which other humans refer to you), although Git does not
+enforce or require any particular form. Arbitrary Unicode may be used, subject
+to the constraints listed above. This name has no effect on authentication; for
+that, see the `credential.username` variable in linkgit:git-config[1].
+
+In case (some of) these environment variables are not set, the information
+is taken from the configuration items `user.name` and `user.email`, or, if not
+present, the environment variable EMAIL, or, if that is not set,
+system user name and the hostname used for outgoing mail (taken
+from `/etc/mailname` and falling back to the fully qualified hostname when
+that file does not exist).
+
+The `author.name` and `committer.name` and their corresponding email options
+override `user.name` and `user.email` if set and are overridden themselves by
+the environment variables.
+
+The typical usage is to set just the `user.name` and `user.email` variables;
+the other options are provided for more complex use cases.
