The data type of the verbose variable is integer and can be negative,
replace improperly used cases in a unified manner:
 1. if (verbose)        => if (verbose > 0)
 2. if (!verbose)       => if (verbose <= 0)
 3. if (XX && verbose)  => if (XX && verbose > 0)
 4. if (XX && !verbose) => if (XX && verbose <= 0)
