8af2b2b89f No newline after Flags in usage
The flags usage template from pflags has a trailing \n. We need to
include a newline in case there are no flags in our template. This will
trim the newline from the end of the flags from pflag and we can do it
right outselves.

After --help will show
```

3eac1434ef Update IsAvailableCommand checks
This slightly changes IsAvailableCommand in that a non-runnable command
with a runnable subcommand is now 'Available'

We also use IsAvailableCommand in the rest of the codebase instead of
half kinda sorta doing it incorrectly other places.

6d2f1d2fa7 Ability to hide commands from usage/help text
Added the ability to have hidden commands that cobra will still run as intended, however they won't show up in any usage/help text

adding internal field to command

private is a better name

hiding private commands in default help/usage

opting for 'hidden' over 'private'

updating all 'help command' checks to exclude hidden commands

updating how commands are displayed in usage/help text by updating/adding some methods. added tests for hidden/deprecated commands

making command hidden when testing hidden command execution

test now leverage the included suite and are much less custom. also removed deprecation tests, once I discovered them in cobra_test.go

updating hidden command test to be more reliable

removing unnecessary () when checking len(c.Deprecated)

updating command comments to be godoc friendly

c2d19e9c43 Use the HelpFunc for the --help flag
We were just calling Help() when a user set the --help flag. You could
overwrite how the help subcommand worked with SetHelpFunc, but not now
the --help flag worked.

27bf24802c Redo HelpFunc() to work things other than the help subcommand
Today the HelpFunc() seemed to be tailor built for the `help`
subcommand. Which has a rather weird purpose as its `Run` needs to
find the actual command we want to get help about.

Instead make the HelpFunc() for a command be about that command,
rather than having it search for some other command...

e8bd799c1c Display pflag.CommandLine flags as if they were declared on the parent
```go
package main

import (
	"github.com/spf13/cobra"
	"github.com/spf13/pflag"
)

func main() {
	cmd := &cobra.Command{
		Use:   "min",
		Short: "minimal command",
		Run:   func(_ *cobra.Command, _ []string) {},
	}

	pflag.String("oncmdline", "oncmdline", "oncmdline")
	cmd.Execute()
}
```

Is a minimal cobra program.  When --help is displayed without this patch
you only get:

But with the patch --oncmdline is shows under flags.

f453e878d4 Update help template
The template had gotten out of control. It was basically unparsable.
This does a little more work in functions and a little less in the
template. Overall it should be basically the same. It might output the
'additional help topics' in a couple of fewer places, but I doubt people
complain too much...

9a9d01c9ec Better error message
Calling `cobra-test echo times one two turkey` where `one` and `two` are
valid arguments but `turkey` is not now results in.

Error: invalid argument "turkey" for "cobra-test echo times"
Run 'cobra-test echo times --help' for usage.

6f735782e0 Remove unused ErrHelp check
Inside Command.Execute() we were checking for pflag.ErrHelp. But
Command.execute() never returns that value. It just complicates the code
and isn't used.

d0bb3e33e6 rework Find() to make it more obvious what is happening
We had lots of quirky if statements like `commandFound.Name() ==
c.Name() && len(stripFlags(args, c)) > 0 && commandFound.Name() !=
args[0]` which embeed all sorts of artifacts which are hard to parse. So
in general, just try to simplify and make stuff readable.

07ad27d239 Handle grand children with the same name as the root
This fixes a problem where if you had a root command and a grand child
with the same name, the parser would break and would not run the
grandchild. The code was special casing if the immediate child had the
same name, but didn't handle grand-children

fb86c5c559 Correctly print the unknown command name
by now, if someone calls: `program --validflag unknowncommand` the
output will be:

```
Error: unknown command "--validflag"
Run 'program help' for usage.
```

This patch strips out flags so the unknown command is printed:

```
Error: unknown command "unknowncommand"
Run 'program help' for usage.
```

794a362808 Remove specail casing in Execute()
We had some stuff that created a new empty []string if args was already
and empty string (why?)

We had some stuff that called Help() if it wasn't runnable (but
.execute() already does that)

Just remove the special case stuff.

bd0f8a846e Stop special casing runnable root commands
The special case code to handle a runnable root command had some
problems.  It was noticed that if you created a runnable root and a
subcommand.  And the subcommand was then executed with both a valid and
invalid flag, the error message was about the valid flag being invalid.
For example

./command subcommand --goodflag=10 --badflag=10

Would fail and tell you that --goodflag was an invalid flag. Instead if
we just do away with the special Command.execute() for the root command
the parser for subcommand is what prints the error and it gets it
right...
