Applying just the one-liner fix to qapi/opts-visitor.c in isolation
already causes a 'make check' failure; a careful read of 2/2 shows that
I was adjusting the expected output of two separate tests, added over
two separate commits, but both with a BUG/FIXME tag. I'm not opposed to
reworking the series to apply the testsuite coverage after the bug fix,
if that is deemed necessary, but would like an opinion from Markus which
way he would prefer (as this is the code he maintains) before causing
myself artificial churn.
