Merge #13872: [docs] Reformat -help output for help2man

7272fdcfe7 [docs] Reformat -help output for help2man (Tim Ruffing)

Pull request description:

  This commit slightly changes the format of the "Usage" strings in CLI
  `-help` messages to meet the expection of the help2man tool, which we
  use to generate man pages. On the way, we remove a few calls to
  `strprintf()`, which became superficial after commit 32fbfda.
