Fix priority of suppressed vs. explicitly output

Fix priority of suppressed vs. explicitly output

It's not clear this is a real bug, but it is a surprise.  If a table is
in the suppressed list, it isn't output, even if it is in the
to-be-output override list.  This latter list is non-empty only if the
user has hand-edited the the program to force an output.  So this patch
makes that list have priority.
