Hello, Work to arrive at one patch (e.g. [1]) is many times non-trivial, even if the patch is. Part of the work is explained in the commit message, but only a tiny amount. For a full explanation of the removal of GNU_ROFF I wrote a blog post with much more detail: https://felipec.wordpress.com/2021/06/05/adventures-with-man-color/ Cheers.
