This fixes an issue where `--quiet` doesn't work with commands that have
subcommands. This is because `config_configure` only looks at the global
and top-level subcommand, and not deeper subcommands. The issue was that
`--quiet` was not defined as a global flag. This was changed in
https://github.com/rust-lang/cargo/pull/6358 in order to give a better
help message for `cargo test --quiet`. I don't remember if clap just
didn't support overriding at the time, or if we just didn't know how it
worked. Anyways, it seems to work to override it now, so I think it
should be fine to mark it as global.
This should bring in `--quiet` more in-line with how `--verbose` works.
This means that `--quiet` is now accepted with `cargo report`,
`cargo help`, and `cargo config`.
This also fixes `--quiet` with `cargo clean gc`.
This should also help with supporting `--quiet` with the new `cargo
owner` subcommands being added in
https://github.com/rust-lang/cargo/pull/11879.
Fixes#12957
This came from #12638 and my many small frustrations from wanting to use
`-n` and not being able to.
We do not have any existing `-n` flags for this to be confused with.
I would wager that `-n` is such an entrenched short flag in build tools that it would
not make sense for us to use it with any other flag.
For a survey of where `-n` is used as a short, see
https://www.gnu.org/prep/standards/html_node/Option-Table.html#Option-Table
This mirrors some of the categories from `cargo help` (the man pages).
There are fewer categories to avoid extra vertical space. Instead, they
are left int the `Options` category but put first.
