feat(help): Show PossibleValue help in --help (#3503)
`-h` (short help) still shows the same.

This gates it behind an `unstable-v4` feature flag to avoid disrupting users who set the help without knowing where all it shows up (particularly derive users where `ArgEnum` is automatically extracting the help).

65b9c88b3c fix: Update app_from_crate for App rename
Instead of just renaming it, I reconsidered what the API should look
like.  A custom separator for author does not make sense positionally
but accepting a name, and defaulting it, does fit with what someone
would expect.

I removed the `_from_crate` suffix because it doesn't seem necessary.
We don't have this kind of naming for the derive.  I feel it cleans
things up this way.

ddac492302 fix: Rename IntoApp to CommandFactory
This is part of the `App` rename.

Previously, I was concerned about not being able to deprecate

For backwards compatibility, we still expose the `IntoApp` name.

c3fec1fa75 fix: Update derive->Command function name
No good solution for transitioning the trate name, unfortnately, since
we can't mark `use`s as deprecated (we can, it just does nothing).

I got rid of the `into` prefix because that implies a `self` parameter
that doesn't exist.

4895a32e81 fix: Deprecate SubcommandRequiredElseHelp
Now that we can use `SubcommandRequired |
ArgRequiredElseHelp`, this setting offers little value but requires we
track required subcommands with two different settings.  Deprecating as
the cost is not worth the benefit anymore.

Issue #3280 will see the derive updated

06d43a02da fix(help): Subcommand help looks like --help
Like was said in #2435, this is what people would expect.

While we should note this in a compatibility section in the changelog, I
do not consider this a breaking change since we should be free to adjust
the help output as needed.  We are cautious when people might build up
their own content around it (like #3312) but apps should already handle
this with `--help` so this shouldn't be a major change.

We aren't offering a way for people to disable this, assuming people
won't need to.  Longer term, we are looking at support "Actions" (#3405)
and expect those to help customize the flags.  We'll need something
similar for the `help` subcommand.

272f840178 feat: Replace core set of AppSettings with functions
This is a part of #2717

Some settings didn't get getters because
- They are transient parse settings (e.g. ignore errors)
- They get propagated to args and should be checked there

`is_allow_hyphen_values_set` is a curious case.  In some cases, we only
check the app and not an arg.  This seems suspicious.

5290f82133 feat: Override DeriveDisplayOrder behavior with App::next_display_order

with a flatten.  Until we offer app attributes on arguments, the user can workaround with
this no-op flattens.

c00f71ec4a feat: Add App::next_help_heading
This clarifies the intent and prepares for other functions doing the

The deprecation is waiting on 3.1.

This is part of #1807 and #1553.

9d482d00ba feat(error): Show possible values when none are supplied
This is inspired by cargo which allows you to run `cargo test --test`
and it will list the possible tests (obviously we can't support that atm
because that requires a lot of runtime processing).  When we do have a
static list of possible values, we can at least show those.

06aa418fa6 fix(error): Be more accurate in smart usage
For some errors, we use the unroll logic to get the list of required
arguments.  The usage then does the same, but without a matcher.  This
was causing the lists to not match.

As a side effect, this fixed an ordering issue where we were putting the
present arg after the not-present arg.  I assume its because we ended up
reporting the items twice but the first time is correctly ordered and
gets precedence.

This was split out of #3020

fix(help): Optional arg values in brackets
When an Arg uses .min_values(0), that arg's value(s) are effectively
optional. This is conventionaly denoted in help messages by wrapping the
arg's values in square brackets. For example:

    --foo[=value]
    --bar [value]

This kind of argument can be seen in the wild in many git commands; e.g.
git-status(1).

c6664afe9d fix(parser): Track the most explicit value source
We were only tracking the last value source (default, env, cli, etc).
This works for args because they only come from one source.  Groups
however can come from multiple sources and this was making us treat a
group with a default value as being completely from defaults despite
some values maybe being from the commandline.

We now track the highest precedence value for a group.

38e6952d46 fix: Don't panic when propagating
I thought I was adding a test in #3305.  Maybe I considered the
clap_complete changes sufficient for this.  Doing more `debug_assert`s
would be good also.

Unsetting `PropagateVersion` helps in some cases but we need to unset it
globally to override the global propagation.

The error was when doing `#[clap(arg_enum, default_value_t = ...)]`.

Good example of why we should minimize `use`, at least in tests
(besides reducing merge conflicts, code churn, etc).

e5fbdc9b95 Revert "Remove {n} support"
This reverts commit 333b993481.

PR #1810's motivation was effectively "this is redundant with `\n`".
That is a fine motivation.  Unfortunately, we don't have a way to force
a hard break in `clap_derive`.  #2389 should help with this eventually
but we shouldn't hold up 3.0 to get that ready.  So in the mean time, we
are restoring `{n}`.

We have #3230 for tracking the re-removal of it.
