wide-format option to get client-side ops and cache statistics on a single
line.
Change client side ops to the number of attempted ops, whether cached or
not, rather then just the number of rpc's that went through to the server.
This brings nfsstat inline with systat -vm and vmstat and reduces
confusion. The combined cache percentage stats now available via
'nfsstat -cW 1' becomes very useful.
