Hi Eric, Junio,

thank you very much for your feedback! I honestly apologize I
got so many things wrong.

Nothing to apologize. You are not expected to know all the local
conventions from the beginning, and we appreciate your willingness
to adjust ;-)

I'll try to minimize the scope a little bit for the next attempt to
make sure my approach is good first and then expand:
i.e will only teach git branch to delete "-" & give out an
error message in case there is no previous branch
to make sure I got the basics correct.

Sounds good.
