This commentary is not needed here, so please remove it.

Also, please note that our conventions are to end a comment in a
period and two spaces.

> +  symbol = Findirect_variable (symbol);
> +  CHECK_SYMBOL (symbol); /* BUG#00000 Must guard SYMBOL_TRAPPED_WRITE_P */

This comment is also redundant: the fact that we check a symbol
doesn't need any explanations.

Thanks.
