Only the first of those is even valid here, if you double-quote an identifier it never is even possibly considered a keyword that could conflict.  As for the first one, our reserved words specification doesn’t claim commit as one of them.  Bugs need to things where we claim one thing and implement something different.  Not relative to some external specification.
