Oh well. I don't like this very much, but removing things like this
would ultimately end in having a flat XML output structure and using
indentation adjustment to have correct indentation across the xml, which
is somewhat controversial. Well, it doesn't affect functionality, so
it's not a show-stoping issue.
I don't like how VIR_CPU_FORMAT_EMBED[D]ED was used either. So on
review, I think it's better to split this one into multiple functions,
specifically catering to each caller, with each embeddable call-point
starting at 0 indentation.
Otherwise, this patch works correct, so ACK.
I went ahead and squashed this in before pushing.
