Make isValidGlobPattern recognize ** (#7682)
#7645 added support for `**` matching path separators, but didn't update `isValidGlobPattern` for `--suppress` to enable it. This also updates test cases and makes `isValidGlobPattern` more correct and robust overall. In particular multiple consecutive `?` for a glob is absolutely valid and frequently useful to ensure exactly or at least some number of characters. --------- Co-authored-by: Joel Johnson <[email protected]> Co-authored-by: Daniel Marjamäki <[email protected]>
