Hi,
Junio, you are the leader. And I really don't want to bother you with
my opinions.
I am just trying to make you satisfied so gitsters, I mean git users,
will have this feature as soon as possible.

I was NOT trying to scare with my message. That paragraph was meant
to let people who would need to do something ("no common paths") know
what they will need to do. I think it is good enough because "mostly
common paths" people will be happy too by knowing that everything is
unchanged as they want it to be. So I haven't thought about scaring
at all. I thought it was good indeed! :-)

Just to clarify my point-of-view about the design:
I do prefer my first design mainly because it mimics the state of an
initial commit. I think that is subjectively better.
You have been asking me to make one of the two possible work flow uses
you pictured as favored so things will be already set to them. No
further commands to them.
I did it! As a matter of fact the "mostly common paths" people were
favored as you have noticed your inclination to it before.
As I told you, I just want to make you happy so people that needs the
feature I am working on could have it as fast as possible.
And if one of the possible work flows have to be favored then I do
agree with you about "mostly common paths" as the best choice.
But the point is that the other group will need to do further commands
anyway so I would keep my previous design because of the resemblance
to an initial commit: work tree full and nothing added to the index.
But I mean it! I really want to satisfy you. So this was the last
time I talk about my preference.
Therefore let's find out what you want me to do so we can finish this
production cycle. I don't want to bother you anymore.

I was trying to be concise on my message. I realize you want it more explained.
What about that:
After the 'checkout -o -b' you are in an new unborn branch ready to be
committed. The next commit will start a new history without any
ancestry. If this new branch was made to start from scratch, not
resembling the previous one, then you should use 'git rm -rf' to get
an empty work tree and index. Otherwise with a 'git commit -a' you
will have a tree exactly as in the previous branch. So just set
things as you want it to be and commit the new unparented branch.

I agree with you in choosing "mostly common paths" as the target since
you have decided to target one.
Before I send another patch version could you please tell me your
position about my new explaining text up there. I will wait for your
reply before sending a new patch version.
Best regards
