But you cannot know which ones you have to give, unless you parsed
output of git-repo-config!
Why?
I was suggesting that you would literally write something like
this in your script:
git-whatchanged --name-status "$1".."$2"
Then whatchanged uses the '--name-status', and ignores whatever
is in the repository configuration, so you do not need to care
what repo-config says. Neither used are its built-in defaults.
