Russ Cox b5ddc42b46 io/fs, path, path/filepath, testing/fstest: validate patterns in Match, Glob ... According to #28614, proposal review agreed in December 2018 that Match should return an error for failed matches where the unmatched part of the pattern has a syntax error. (The failed match has to date caused the scan of the pattern to stop early.) This change implements that behavior: the match loop continues scanning to the end of the pattern, even after a confirmed mismatch, to check whether the pattern is even well-formed. The change applies to both path.Match and filepath.Match. Then filepath.Glob and fs.Glob make a single validity-checking call to Match before beginning their usual processing. Also update fstest.TestFS to check for correct validation in custom Glob implementations. Fixes #28614.
