From: Karthik Nayak <redacted> Since 'ref-filter' only has an option to match path names add an option for plain fnmatch pattern-matching. This is to support the pattern matching options which are used in `git tag -l` and `git branch -l` where we can match patterns like `git tag -l foo*` which would match all tags which has a "foo*" pattern.
