## Description
adds extensible options to folder-level scopes that allows the caller to specify whether they want a
prefix-comparison matcher or a contains-comparison matcher.
Also corrects the behavior of the prefix filter so that it accurately follows the "target is prefix of input" specification, rather than the reverse.
