d3f5d7ce34 fix: Clarify Arg/ArgGroup id's role
This adjusts names.  Adjusting the derive naming (and re-naming) is left
to #2475.

Fixes #3335

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.

9bd7060089 fix: Deprecate various APIs
- ArgSettings are part of #2717
- Errors are part of #2628
- `help_heading` is part of #1807 and #1553
- Some misc parts are for API consistency

6c60b79d21 fix(assert): Provide next steps for '-h' conflicts
For now, we are going to provide a better debug assert in this case.
Resolving #3405 is the better long term route.

c00f71ec4a feat: Add App::next_help_heading
This clarifies the intent and prepares for other functions doing the
same, like `next_display_order`.  This will then open us to name
`subcommand_help_heading` and `display_order` similar.

The deprecation is waiting on 3.1.

This is part of #1807 and #1553.

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).

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.

Fixes #3310

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.

bfc486501a test: Panic, rather than exit, on error
Working on a fix for #3217 and can't see what is failing because the
test process exits.

9e64387ef0 revert(help): Partial revert of 3c049b4
The extra whitespace was targeted at machine processing for a subset of
users for a subset of runs of CLIs.  On the other hand, there is a lot
of concern over the extra verbose output.

A user can set the help template for man, if desired.  They can even do
something (env? feature flag?) to make it only run when doing man
generation.  We also have #3174 in the works.

So let's focus on the end-user reading `--help`.  People wanting to use
`help2man` have workarounds to do what they need.

Fixes #3096

19ed78c64f fix(help): Don't commit to '--help' that doesn't work
We have two ways of fixing this
- Making `--help` work
- Don't put `--help` in the help output

For now, I went with the latter.  I tried to make it clear what the
actual requirement is so we can pivot if needed.

Fixes #2892

This happens to also fix the interaction of `DisableHelpFlag` with the
help subcommand and complcations.  I've added a test to help catch if we
break this by changing how we fixed the original issue.

Fixes #2724

These issues were reported against clap3.  I've not tried to reproduce
these in clap2 to see if they should show up in the release notes.

045bf99ae0 test: Consolidate builder tests
This is prep for moving the derive tests.  Besides organizing the test
folder for each API, this should reduce link time at the cost of
re-compiling more when a test changes.
