Confusing --graph --all output with detached branches

Confusing --graph --all output with detached branches

[Bjørnar Snoksrud]

If you end up with a history containing commit A with parent B, where
a detached branch is merged into A while an unrelated branch branches
off of B, you will get the following output:

$ git log --graph --all
*   commit ff4265fcbfe94a2abe93c97d86e0d9f0e0a136cb

      1

-

Which is pretty informative  - after '2' we branched out for commit 3,
and the branch containing 4 and 5 was merged into master.

However, if you use the pretty common `one line` git log alias, you get this:

*   ff4265f  (HEAD -> master) Merge branch 'bar'
|\
| * 0bbc311  (bar) 5
| * b1c9c49  4
| * ce053f9  (foo) 3
|/
* 8b62de9  2
* cb7e7e2  1

.. which indicates that `foo` is contained within `bar`. Maybe

*   ff4265f  (HEAD -> master) Merge branch 'bar'
|\
| * 0bbc311  (bar) 5
| * b1c9c49  4
|
| * ce053f9  (foo) 3
|/
* 8b62de9  2
* cb7e7e2  1

.. would be better?

Reproduction steps:

git init
git commit --allow-empty -m 1
git commit --allow-empty -m 2
git checkout --branch foo
git checkout -b foo
git commit --allow-empty -m 3
git checkout --orphan bar
git commit --allow-empty -m 4
git commit --allow-empty -m 5
git checkout master
git merge bar -m merge
git log --graph --all  --pretty=format:'%Cred%h %C(yellow)%-d%Creset %s '

Yes, it would be.

Another possibility would be to shift the columns between 4 and 3.
