This enables clap's [wrap-help] feature and sets max_term_width to wrap after 100 columns (the value clap is planning to default to in clap-v5). This commit also adds blank lines which cause clap to split longer doc comments into separate help (displayed for `-h`) and long_help (displayed for `--help`) messages, as per [doc-processing].
