  # ripgrep has many options which negate the effect of a more common one — for
  # example, `--no-column` to negate `--column`, and `--messages` to negate
  # `--no-messages`. There are so many of these, and they're so infrequently
  # used, that some users will probably find it irritating if they're completed
  # indiscriminately, so let's not do that unless either the current prefix
  # matches one of those negation options or the user has the `complete-all`
  # style set. Note that this prefix check has to be updated manually to account
  # for all of the potential negation options listed below!
