pt-query-digest progress is hard to disable

[Baron Schwartz]

pt-query-digest's --progress option is hard to silence for use in cron jobs where output is undesired. The following disables the progress output:

--progress=''

But it doesn't disable this warning, which apparently comes from Getopt::Long:

 Option progress requires an argument

So the only way to avoid output in my cron job is a workaround such as this:

--progress=time,1000000

--progress=none? or add --quiet to pqd?

[Baron Schwartz (baron-xaprb)]

I think adding --quiet would be fine.
