Incur's `alias` map registers one-letter short flags and already accepts
kebab-case spellings of camelCase options. Twenty options registered their
kebab-case long name as an "alias", so help and completions advertised
flags such as `-case-sensitive` and `-relative-path` that the parser reads
as stacked short flags and rejects with "Unknown flag: -c".
