It's probable that we had all these before and marked them manually in
the coverity UI as false positive but loplugin:flatten (or somethine
like that) changed the code enough that coverity doesn't recognize it
as the same code anymore and warns about them again.

I don't know a good way to inline mark these up to avoid the warning,
but they are manually set as ignored again and so shouldn't appear in
the next run.
