[minor] Preserve whitespace and add branch as an input (#9)

* preserve whitespace
this is important for md files where whitespaces represent line breaks

* add branch as an input

* move branch down to when we create the new one
it might not be the right thing...

* use github ref for dry run

* roll back changes and just make the pr work from the passed base branch

* lint
