Re: [StGit PATCH 9/9] Use the default git colouring scheme rather than specific scripts

> This patch adds the mechanism to check if the output is tty for the
> diff and show commands and passes the --color option to git if the
> color.diff config option is set auto or true. The patch also changes the
> default pager to 'less -FRSX' from the diffcol.sh script.
