Display (overall) averages for per-module statistics as well as for
per-program statistics.

Also, with `-d' (default; `-n' to turn off) compute geometric standard
deviations and display +/- 1 s.d. points as well as average.  Note that
since these are *geometric*, the lower point will appear closer to the
average than the upper.  This is correct behaviour.
