Remove ':Print' command #3049

There's no way this isn't some long-running joke:

  "Just as ':print'.  Was apparently added to Vi for
  people that keep the shift key pressed too long..."
  Note: A user command can overrule this command.

Regarding ':X': the command has been removed for a while, but the
documentation must have been missed, so remove it here.
