Subject: [PATCH] Fix indentation problem with _asyncify

If the input to `_asyncify` contains newlines, the strategy of indenting
and then truncating the first 8 characters won't work, since the first,
empty line doesn't get indented. Instead I've changed the format string
to accept the normal output of textwrap.indent() without modification.
