Show branch in the output of `git log -G foo`-CodePudding

How to show the branches which contain the commit in the output of git log -G foo?

Up to now it looks like this:

commit a24dc0cd5403b697634976f2f7eef4aa7af61b3d
Author: Thomas Guettler <[email protected]>
Date:   Mon Aug 8 11:16:30 2022  0200

    use timezone, and two tests for one day.

    removed debug code.

I would like it to look like this:

Branches: feature-foo

One way to get the branches that contain said commits is to add --simplify-by-decoration :

# to make sense of how branches relate one to another :
git log --graph --oneline --simplify-by-decoration -G foo

# you can also add '-p' to see the content of selected commits, and you will see that
# the commits are not named individually

# to get just the ref names :
git log --format="%D" --simplify-by-decoration -G foo

The above commands will list any ref (local branches, remote branches, tags, stash ...) that appear in your history.
You can add --decorate-refs=refs/heads to list only local branches (or --decorate-refs=whatever/suits/your/needs).

Out of the box, Git cannot embed a shell script in its pretty-format string. Here is a quick & dirty solution. It kind of mimics the format you want, but without colour and without some of the extra information Git might print in certain situations. But I hope it gives you a clue how to continue and refine it.

Preconditions:

You use a UNIX-like shell, I tried Git Bash on Windows.
You use GNU sed.

Define this shell function in your profile or directly on the console:

git_log_branches() {
  git log --pretty=format:"commit %H%nAuthor:   %an
