In this case the executable is `kubectl-plugin`, but we run it as:
kubectl plugin
And the help text should reflect the actual usage of the command.
To create a plugin, add the cobra.CommandDisplayNameAnnotation:
rootCmd := &cobra.Command{
Use: "plugin",
Annotations: map[string]string{
cobra.CommandDisplayNameAnnotation: "kubectl plugin",
}
}
Internally this change modifies CommandPath() for the root command to
return the command display name instead of the command name. This is
used for error messages, help text generation, and completions.
CommandPath() is expected to have spaces and code using it already
handle spaces (e.g replacing with _), so hopefully this does not break
anything.

* Replace all non-alphanumerics in active help env var program prefix
There are other characters besides the dash that are fine in program
names, but are problematic in environment variable names. These include
(but are not limited to) period, space, and non-ASCII letters.
* Another change in docs to mention non-ASCII-alphanumeric instead of just dash
Fixes#2060
When a command sets `DisableFlagParsing = true` it requests the
responsibility of doing all the flag parsing. Therefore even the
`--help/-f/--version/-v` flags should not be automatically completed
by Cobra in such a case.
Without this change the `--help/-h/--version/-v` flags can end up being
completed twice for plugins: one time from cobra and one time from the
plugin (which has set `DisableFlagParsing = true`).

Currently, only one of the persistent pre-runs and post-runs is executed.
It is always the first one found in the parents chain, starting at this command.
Expected behavior is to execute all parents' persistent pre-runs and post-runs.
Dependent projects implemented various workarounds for this:
- manually building persistent hook chains (in every hook).
- applying some kind of monkey-patching on top of Cobra.
This change eliminates the necessity for such workarounds
by allowing to set a global variable EnableTraverseRunHooks.

This fixes an issue with program names that include a dot, in our case
`podman.exe`. This was caused by the change in commit 6ba7ebbc.

Use temporary files instead of assuming the current directory is
writable. Also, if creating a temporary file still returns an error,
prevent the test from failing silently by replacing `log.Fatal` with
`t.Fatal`.
The use in generated bash completion files is getting flagged by
Lintian (the Debian package linting tool).

Although it is not the recommended approach, sourcing a completion
script is the simplest way to get people to try using shell completion.
Not allowing it for zsh has turned out to complicate shell completion
adoption. Further, many tools modify the zsh script to allow sourcing.
This commit allows sourcing of the zsh completion script.

PowerShell 7.2 has changed the way arguments are passed to executables.
This was originally an experimental feature in 7.2, but as of 7.3 it is
built-in. A simple "" is now sufficient for passing empty arguments, no
back-tick escaping is required.
Fixes#1849
