Thanks for the thorough review!
I have adjusted the commit messages and updated the documentation changes.
I'm in trying to add tests, I'll probably have some issues but will
post something that works soon.
As for the comments on behavior, see my responses below.

I moved it to be with the other variables that had configuration
options, but I will move it back.

If you think it should be relocated, I will address in a separate patch.

I followed the code for blame.showRoot and blame.blankboundary.
I think the desired behavior for the other switches would go in a
separate patch, the question is should it precede this one adding
'blame.showemail'?

Agreed, but again I don't see tests for the other switches with options.
