It still looks jarring:

  +(seq RX...)    Match the RXs in sequence.  Alias: :, sequence, and
  +(or RX...)     Match one of the RXs.  Alias: |
  +
  +(zero-or-more RX...) Match RXs zero or more times.  Alias: 0+
  +(one-or-more RX...)  Match RXs one or more times.  Alias: 1+
  +(zero-or-one RX...)  Match RXs or the empty string.  Alias: opt, optional

Honestly, they look like incorrect English: a sentence, starting with
a capital letter, but not ending with a period.  I hope you will
reconsider.
