Thanks for this! A few comments below:

This is fine by me.

The original reason for this is to accommodate "unknown" lines which
were not generated by the test itself (e.g, a KASAN report or BUG or
something). These are awkward, as sometimes they're a useful thing to
have as part of the test result, and sometimes they're unrelated spam.
(Additionally, I think kselftest will indent these, as it indents the
full results in a separate pass afterwards, but KUnit won't, as the
level of nesting is done during printing.)

Personally, I'd rather leave this as is, or perhaps call out "unknown"
lines explicitly, e.g:
Additionally, all lines in a subtest (except for 'unknown' lines)
should be indented...

Thoughts?

Looks good here, cheers.
