I find a fraction, ie. 0.01 = 1% more natural, so I changed it back to
that. I realize this is bike-shedding, but I believe Robert also found
this more natural, as that's what he suggested upthread.
I edited the comments and variable names a little bit, and also added a
small paragraph to the pgbench user manual about this under
"Per-Transaction Logging", in addition to the explanation under
"Benchmarking Options"
