Firstly, thanks for reviewing my patches. I have even checked out the
other reviews
and improvised the other patches according to reviews as well.
I had a few doubts about this one though.

Sorry, but can you explain this a bit more?

Then to have a faithful conversion, IMO, deleting the above lines
would be the correct way?

Thanks for pointing that out. That surely reduced a child_process.
Although the path of the config file for the case of submodules
would be constructed by "%s/config".
