--match pattern

Only consider tags matching the given glob(7) pattern, excluding the "refs/tags/" prefix. If used with --all, it also considers local branches and remote-tracking references matching the pattern, excluding respectively "refs/heads/" and "refs/remotes/" prefix; references of other types are never considered. If given multiple times, a list of patterns will be accumulated, and tags matching any of the patterns will be considered. Use --no-match to clear and reset the list of patterns.
