Small suggestion for improved clarity in Pattern Brushes documentation

[Boldline]

This is a minor thing, but I felt the paragraph might read better to explain that a third and/or a fourth object can be used. the "third" is skipped in the original writing and at first, had me going back to see where it was mentioned that I might have overlooked.

@Boldline yes, I think this can be clarified.
But the idea remains the same: first object repeats, second and third are for start / end. And a fourth can be used as a spacer.
