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.
```

8a18f25809 Auto generation of markdown docs!
An example from the kubernetes project, for the `kubectl config`
command, which as subcommands, and flags, and all sorts of stuff, it
will generate markdown like so:

config modifies .kubeconfig files

config modifies .kubeconfig files using subcommands like "kubectl config set current-context my-context"

```
kubectl config SUBCOMMAND
```

```
      --envvar=false: use the .kubeconfig from $KUBECONFIG
      --global=false: use the .kubeconfig from /home/username
  -h, --help=false: help for config
      --kubeconfig="": use a particular .kubeconfig file
      --local=false: use the .kubeconfig in the current directory
```

```
      --alsologtostderr=false: log to standard error as well as files
      --api-version="": The API version to use when talking to the server
  -a, --auth-path="": Path to the auth info file. If missing, prompt the user. Only used if using https.

      --client-certificate="": Path to a client key file for TLS.
      --client-key="": Path to a client key file for TLS.
      --cluster="": The name of the kubeconfig cluster to use
      --context="": The name of the kubeconfig context to use
      --insecure-skip-tls-verify=false: If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure.
      --log_backtrace_at=:0: when logging hits line file:N, emit a stack trace
      --log_dir=: If non-empty, write log files in this directory
      --log_flush_frequency=5s: Maximum number of seconds between log flushes
      --logtostderr=true: log to standard error instead of files
      --match-server-version=false: Require server version to match client version
      --namespace="": If present, the namespace scope for this CLI request.
      --password="": Password for basic authentication to the API server.
  -s, --server="": The address and port of the Kubernetes API server
      --stderrthreshold=2: logs at or above this threshold go to stderr
      --token="": Bearer token for authentication to the API server.
      --user="": The name of the kubeconfig user to use
      --username="": Username for basic authentication to the API server.
      --v=0: log level for V logs
      --validate=false: If true, use a schema to validate the input before sending it
      --vmodule=: comma-separated list of pattern=N settings for file-filtered logging

5c9146990b Explicitly support local flags overwriting persistent/inherited flags
The current (desired) behavior when a Command specifies a flag that
has the same name as a persistent/inherited flag, is that the local
definition takes precedence. This change updates the various
Flag subset functions to respect that behavior:
* LocalFlags: now returns only the set of flags and persistent flags
  attached to the Command itself.
* InheritedFlags: now returns only the set of persistent flags inherited
  from the Command's parent(s), excluding any that are overwritten by a
  local flag.
* NonInheritedFlags: changed to an alias of LocalFlags.
* AllPersistentFlags: removed as not very useful; it returned the set
  of all persistent flags attached to the Command and its parent(s).

Default UsageTemplate updated to use LocalFlags and InheritedFlags

9b6c92647a When no subcommands are registered, omit command help output
For a single root command with a Run method, the help output still
contains 'help [command]' as a subcommand (because Help is always
added). Since the only subcommand would be 'help', the help is better
off omitted.

This change allows a command to be used both as a subcommand
or a root command without having to define a custom help that elides
the help command when no subcommands are added.  Instead, the default
help command is only added when subcommands are present.

667c348dbd Test behavior for subcommand with same name as root command
If, for some reason, you have an application with some name "foo", and your
app has a subcommand "foo", cobra should behave properly when you call
"foo foo", and it should also behave if you call "foo f".

These changes verify both of these cases and ensure cobra responds properly.

96d543cf2c Reset root command lists in testing
This fixes some issues that appear when testing prefix invocations. Since the
root command lists weren't being cleared, the list would persist between
tests, so there would be multiple instances of each command. Then, if you
tried to match a prefix of one of those commands, you'd get two matches (one
for each instance) and the command would fail.

Resetting the root command lists prevents them from persisting between tests,
resolving this issue.
