This is a grave mistake from my side. Though I do not understand how
will `quiet` be counted twice. Let's say we pass `--quiet` option in the
command, then `quiet` is set to 1. And now if we do `quiet|= OPT_QUIET`,
this will make `quiet` 1 again right? Could you please tell me what am I
missing out here?

The fix you suggested (quiet ? OPT_QUIET : 0), we use this because we
want to ensure `quiet` goes into sync as either 1/0 right? Not any other
non-zero positive integer right?
