Simplify pattern tests
- Stop using “adjust_pattern” and “exclude_path” as they're utility functions not relevant to testing pattern classes - Cover a few more cases, especially with more than one path separator and relative paths - At least one dedicated test function for each pattern style as opposed to a single, big test mixing styles - Use positive instead of negative matching (i.e. the expected list of resulting items is a list of items matching a pattern)
