BTW, I'm fine with Tom's bare-word with WITH idea. That seems to be the
most consistent with everything else. Is there a problem with doing
that? I know getting syntax is one of the hard parts of new features,

I find that very hard to believe... I would expect a primary use case
for VERBOSE to be "I ran REINDEX, but it doesn't seem to have done
anything... what's going on?" and that's exactly when you might want to
use FORCE.
