Before there was no way to make `SubcommandsNegateReqs` with
`clap_derive` because it required a required field with a sentinel value
for when the required part was negated. We blocked that.
This turned out simpler than I expected.
This came out of the discussion for #2255 but that issue is more
specifically about the panic, so not closing it.
In #2270, its brought up to solve this at the `cargo workspace publish`
level. However, copying the files is a 5s fix without any design work,
it doesn't seem like support within an external tool should block us
from getting this fix into users hands. Once `cargo workspace publish`
supports this and if we are still using it, we can re-evaluate.
Fixes#2270
* Check for `DisableHelpFlag` along with `NoAutoHelp`
Also applies for `DisableHelpSubcommand` and `DisableVersionFlag` with `NoAutoVersion`
* Add tests for overriding help and version, and disabling version.
These override by disabling the default and adding a new one.
* Don't use `default_missing_value` for `override_version_using_short`
* Check errors by the API.
This changes the `disabled_version_long` and `disabled_version_short` tests.
This is opposed to comparing the stderr output.
The `display-suffix` option for `edit:complex-candidate` was [deprecated in Elvish v0.14.0][1] and
removed in v0.15.0 (latest version is v0.16.3), so this commit changes the Elvish completions
generation to use the `display` option instead.
Additionally, this commit changes assignments to use the `var` and `set` keywords as using
`name = value` without these keywords ('legacy assignment form') [will be deprecated][2].

* feat(arg_value): ArgValue can be used for possible_values
Through the ArgValue it is possible:
* `hide` possible_values from showing in completion, help and validation
* add `about` to possible_values in completion
* Resolved a few change-requests by epage
* make clippy happy
* add ArgValue::get_visible_value
* remove verbose destructering
* rename ArgValue::get_hidden to ArgValue::is_hidden
* add test for help output of hidden ArgValues
* Documentation for ArgValue
There is an issue that required to implement From<&ArgValue> for
ArgValue. We should probably find a solution without that.
* fix requested changes by epage
* fix formatting
* add deref in possible_values call to remove From<&&str>
* make clippy happy
* use copied() instad of map(|v|*v)
* Finishing up for merge, hopefully
* changes requested by pksunkara
This addresses a bug that causes duplicate flags reported in user-facing
error messages when two flags require one-another but also are required
under other conditions. The fix involves removing duplicates in unrolled
requirements, which addresses the user-facing aspect of this bug.
* fix(generate): Better subcommand completion in fish
* Prevent completing subcommands that were already completed
* Make sure all parent subcommands actually existent
Partially fixes#2715
* Added Test
* fix(generate) Improve subcommand testing
This now also disables the completion of sub_subcommands options for
subcommands.
