Yeah, neither is particularly optimal. Every now and then (a couple
years, say) you do have to re-evaluate false positives, so it's better
to fix them if possible. On the other hand the code is uglier.
Let's ignore these in Coverity---with a triaging comment there about why
they are false positives.
