Please review a small enhancement when reporting bad options on the command line.
[JDK-8313693](https://bugs.openjdk.org/browse/JDK-8313693) introduced code to help determine a list of suggestions when given a misspelled word and a vocabulary of possibly intended words. It was added in the context of reporting bad/invalid tags in doc comments. This fix leverages that code by applying it to unrecognized command-line options, comparing them against the set of supported command-line options. Now, when an unknown command-line option is found, the code will report possible suggestions, and a reference to `--help` instead of just simply listing the full command-line help. ------------- Commit messages: - JDK-8323016: Improve reporting for bad options Changes: https://git.openjdk.org/jdk/pull/17274/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=17274&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8323016 Stats: 106 lines in 3 files changed: 103 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/17274.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/17274/head:pull/17274 PR: https://git.openjdk.org/jdk/pull/17274
