`never` if you prefer git commands not to use color unless enabled
explicitly with some other configuration or the `--color` option.
+column.ui::
+ Specify whether supported commands should output in columns.
+ This variable consists of a list of tokens separated by spaces
+ or commas:
++
+--
+`always`;;
+ always show in columns
+`never`;;
+ never show in columns
+`auto`;;
+ show in columns if the output is to the terminal
+`plain`;;
+ show in one column
+--
++
+ This option defaults to 'never'.
+
commit.status::
A boolean to enable/disable inclusion of status information in the
commit message template when using an editor to prepare the commit

+NAME
+----
+git-column - Display data in columns
+
+SYNOPSIS
+--------
+[verse]
+'git column' [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
+ [--indent=<string>] [--nl=<string>] [--pading=<n>]
+
+DESCRIPTION
+-----------
+This command formats its input into multiple columns.
+
+OPTIONS
+-------
+--command=<name>::
+ Look up layout mode using configuration variable column.<name> and
+ column.ui.
+
+--mode=<mode>::
+ Specify layout mode. See configuration variable column.ui for option
+ syntax.
+
+--raw-mode=<n>::
+ Same as --mode but take mode encoded as a number. This is mainly used
+ by other commands that have already parsed layout mode.
+
+--width=<width>::
+ Specify the terminal width. By default 'git column' will detect the
+ terminal width, or fall back to 80 if it is unable to do so.
+
+--indent=<string>::
+ String to be printed at the beginning of each line.
+
+--nl=<N>::
+ String to be printed at the end of each line,
+ including newline character.
+
+--padding=<N>::
+ The number of spaces between columns. One space by default.
