Misleading help text for metadata --quiet

[jonhoo]

Problem
cargo metadata --quiet prints to stdout even though --help says

OPTIONS:
    -q, --quiet                          No output printed to stdout

Steps

1. cargo metadata --help
2. cargo metadata --quiet
3. Observe that stdout is not empty

Possible Solution(s)
Obviously, --quiet meant to indicate that no cargo messages are printed to stdout (or maybe stderr) like "Updating index". But, the way it's written, it clearly implies that no output should go to stdout.

Notes

Output of cargo version: cargo 1.47.0 (f3c7e06 2020-08-28)

Hi @jonhoo, can you please share the message that fits this scenario?

Thanks

Hmm, how about:

Do not print cargo log messages.

Looks good to me. Thanks

This also applies to cargo build --quiet, cargo run --quiet, cargo test --quiet, cargo bench --quiet, cargo doc --quiet, and possibly other commands. They are all documented as "No output printed to stdout", but warnings, errors, test results, ..., are shown.
