Eliminate the displaying zero stats when the explicit protocol

When a particular protocol is specified and either

This cause any useful data to be scroll off the screen.
Sound like good fixes.
With this patch only non-zero stats will be shown, which
makes the output of these options more condensed and
in turn more useful.
Couldn't this make the output harder to parse? E.g. if you want to know
how many getattr's were sent each second, it might be simpler if you say
a 0 those times when there were no getattrs.
Maybe.. but if one was parsing the output and the parser didn't see a
gettr stat, I'm assuming it would not increment the "gettr counter"
so it would be know there were zero gettars in that time period..
The main reason I did this was, when watching reads and writes, 90% of
the output was zeros stats which made very difficult to see the non
zero counts (i.e. read and write stats) since they generally got
scrolled of the screen...
Also note, when the --list option is not used, zero stats are
shown in the column output, but granted, the column output
is a bit harder to parse than the list output.
I guess I could change it so non zero stats are show only
the --sleep option is *not* used....
Dare I suggest another commandline argument? I didn't really like the
idea of leaving out the stats with 0's, but after trying it, the output
does look a lot cleaner. Perhaps giving users the choice would be the
way to go.
