+status.showUntrackedFiles::
+	By default, linkgit:git-status[1] and linkgit:git-commit[1] show
+	files which are not currently tracked by Git. Directories which
+	contain only untracked files, are shown with the directory name
+	only. Showing untracked files means that Git needs to lstat() all
+	all the files in the whole repository, which might be slow on some
+	systems. So, this variable controls how the commands displays
+	the untracked files. Possible values are:
++
+--
+	- 'no'     - Show no untracked files
+	- 'normal' - Shows untracked files and directories
+	- 'all'    - Shows also individual files in untracked directories.

+If this variable is not specified, it defaults to 'normal'.
+This variable can be overridden with the -u|--untracked-files option
+of linkgit:git-status[1] and linkgit:git-commit[1].
