It looks less readable in my opinion, and it also isn't "raw output."

This is due to sharing code with kunit_parser.py, which wants to strip leading whitespace since it uses anchored regexes. We could update the kunit_parser.py code to tolerate leaading spaces, but this patch takes the easier way out and adds a bool flag.

Looks good to me. I think we'll probably want to update the parser code to actually keep track of indentation at some point, as it could help with some ambiguity which otherwise would exist when there are nested tests without test plan lines.

For the moment, though, this is definitely an improvement.
