From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>
By default "-V" will be the same as --verbose=info, but since we allow
--verbose to have an option, do the same with -V. -V will only take a
integer arguments though.
Also updated the documentation of --verbose to the names that are actually
used, and not the extended names ("crit" and not "critical", etc).
