Curious, why are you setting this?

Convention I picked up, I think, from the analyzer tests.  The default is a
space maybe?  Setting it like so yields results like this:

PASS: getSdkDir | arg parsing

Making it easy to see the hierarchy...  In the end though it's more habit than
anything.  Happy to revisit! :)
