Appending a plus + to a level name also includes all higher levels.
For example:
dmesg --level=err+
will print levels err, crit, alert and emerg.
Prepending it will include all lower levels.

--time-format may be used multiple times with different values for
format to output each specified format.
The delta always follows ctime or raw if specified together.
