This is a step towards #3309. We want to make longs and long aliases
more consistent in how they handle leading dashes. There is more
flexibility offered in not stripping and it matches the v3 short
behavior of only taking the non-dash form. This starts the process by
disallowing it completely so people will catch problems with it and
remove their existing leading dashes. In a subsequent breaking release
we can remove the debug assert and allow triple-leading dashes.
This commit updates the man page renderer to use a relative margin
indent for environment variable text instead of appending to the
existing help text.

Fixes: #3630
`Command::_build_all` started as an internal function for
`clap_complete` as a stopgap until #2911. Overtime, we've been finding
more cases where this function needs to be called, so now we're going to
fully embrace it until #2911 so people aren't scrared off by the hidden
implementation from using it.
This was inspired by #3602
Comptibility: Though this adds a deprecation which we general reserve
for minor or major versions, this is enough of a corner case that I'm
fine doing this in a patch release.
The long term goals are
- Easier refactoring
- Identify needs for reflection API
Shorter term, if I want to rename `App` to `Command` and deprecate
`App`, it will mark all member access as deprecated. This works around
that.
I gave up in exploring abstractions when it came to `MKeyMap` access.
This can be refined in the future.
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
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.
I have access to the `clap-man` name but we use `clap_*`. Rather than
people getting mixed up on which is supposed to use, we went with a
different name.
