* - The pattern is split to colon-separated components.
* - A component equal to '*' (with nothing else) scores 0 points.
* - A component that's a pattern, otherwise, scores 1 point.
* - A component that's a literal string scores 2 points.
* - The score of a pattern is the sum of the score of its components.
