Firstly, thank you for the feedback Junio and Lars. Secondly, I was
not planning to add recurse to the init/update command, but your
(Lars) suggestion seems really handy; I will implement it in my patch.
About auto-initialization, I, as writing, am implementing it to be
optional and an extra -i has to be specified if the user wants to do
it.

I could not agree more and in fact, I wanted to leave to the user how
they use the recurse command. I basically will be using for status and
diff primarily; and may be for creating and checking out branches; but
as I said it mostly depends on how the user wants to use it.

In fact if I am also thinking whether to add intelligence in such
scenarios. What do you think if we choose DF of BF based on the
command and options?

What is you suggestion in such cases Junio?
