if log-file and really-quiet options were used together it could lead to
a completely empty log-file. this is unexpected because we need the
log-file option to work in all cases and produces at least a log of
verbosity -v -v. this is a regression of commit

move the really quiet check back up, so it's set before the evaluation
of the actual log level, where check for log file, terminal, etc take
place.
