Reject bad command-line options with a non-zero exit status - #884
Conversation
Add DaikonGetopt, a Getopt subclass that throws a UserError describing an unrecognized, ambiguous, or malformed option and handles -h and --help. Use it in Daikon and in the other tools that use Getopt. Remove Diff's -u and -z options, which had no effect. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Previously, Daikon printed an error and the usage message for an unrecognized command-line option, but exited with status 0. Most other tools ignored the bad option and continued. Scripts that invoke Daikon, such as
runcluster.pl(see #856), could not detect the failure.This PR adds
DaikonGetopt, aGetoptsubclass that throws aUserErrordescribing an unrecognized, ambiguous, or malformed option, and that handles-hand--help. Daikon and the other tools that already use Getopt now use it. It also removesDiff's-uand-zoptions, which had no effect (and the corresponding diff-tests goal files).This is the first part of #857, split up for easier review. Follow-up PRs build on it. Unrelated fixes are in #905 (doc spellings) and #906 (test drivers).
