23e2f66 bench: don't return 1 in have_flag() if argc = 1 (Jonas Nick)
96b1ad2 bench_ecmult: improve clarity of output (Jonas Nick)

Pull request description:

  Previously "ecmult{,_multi} xg" meant multiplication with (x - 1) random points
  and base point G. Now
  - xP means multiplication with x random points and
  - xP & G means multiplication with x random points and G
