Output for the help info uses extremely long lines

One example help screen is this:

D:\dev\wgpu-rs>cargo deny list --help
cargo-deny.exe-list 0.5.2
Outputs a listing of all licenses and the crates that use them

USAGE:
    cargo-deny.exe list [FLAGS] [OPTIONS]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
    -v, --verbose    This just determines if log messages are emitted, the log level specified at the top level still
                     applies

OPTIONS:
        --color <color>            Output coloring, only applies to 'human' format [default: auto]  [possible values:
                                   Always, Never, Auto]
    -f, --format <format>          The format of the output [default: human]  [possible values: Human, Json, Tsv]
    -l, --layout <layout>          The layout for the output, does not apply to TSV [default: license]  [possible
                                   values: Crate, License]
    -t, --threshold <threshold>    The confidence threshold required for license files to be positively identified: 0.0
                                   - 1.0 [default: 0.8]

This goes way out to 120, so on a standard 80 col terminal it gets wrapped awkwardly. Even when I put a terminal taking up half the width of my monitor it only ends up being 117 cols wide. Please make the help messages always fit properly within 80 cols, or check the terminal size and fit them to the current terminal size.
