See other PR, this is about coding-style.  One could say even a || !a && b
doesn't make sense as the !a in the !a && b conditon will always be true
and thus this is a || b.

So a diagnostic is warranted - maybe it's wording is not exactly helpful and
"warning: your condition is obfuscated" would be better? ;)
