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.
      --certificate-authority="": Path to a cert. file for the certificate authority.
      --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
```

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...

fd10548830 Fix additional help topics template
The additional help topics were really hard to ever get to show.  The
required conditionals were difficult to meet and did not seem to really
be logical.

Problems I see:
1) the top level command could never have additional topics.
2) you must have at least one sibling command AND one subcommand
3) we had the AND above, but then test both conditionals a second time
4) if the sub command was runnable we wouldn't print anything
5) if the sibling commands were not runnable we wouldn't print anything
4+5) it's possible that we printed "Additional help topics:" with nothing following it
6) We always printed ourselves as a sibling in the additional info

Whew, I think I fixed all of those!  Again, using
https://github.com/eparis/readable-golang-template
I'm actually able to visualize the template and see this craziness.

The conditionals BEFORE this change:

{{if .HasParent}}
        {{if and (gt .Commands 0) (gt .Parent.Commands 1) }}
                Additional help topics:
                {{if gt .Commands 0 }}
                        {{range .Commands}}
                                {{if not .Runnable}}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}
                {{end}}
                {{if gt .Parent.Commands 1 }}
                        {{range .Parent.Commands}}
                                {{if .Runnable}}
                                        {{if not (eq .Name $cmd.Name) }}
                                        {{end}}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}
                {{end}}
        {{end}}
{{end}}

The conditionals AFTER this change:

{{if or (.HasHelpSubCommands) (.HasRunnableSiblings)}}
        Additional help topics:
        {{if .HasHelpSubCommands}}
                {{range .Commands}}
                        {{if not .Runnable}}
                                {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                        {{end}}
                {{end}}
        {{end}}
        {{if .HasRunnableSiblings }}
                {{range .Parent.Commands}}
                        {{if .Runnable}}
                                {{if not (eq .Name $cmd.Name) }}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}

c64442a487 fix usage template conditional
I wrote https://github.com/eparis/readable-golang-template which
converts golang templates into something structured around the
conditionals.  Obviously you can't just USE the output, but you can SEE
the problems.  In this case the output shows something like:

{{if .HasParent}}
        {{if and (gt .Commands 0) (gt .Parent.Commands 1) }}
                Additional help topics:
                {{if gt .Commands 0 }}
                        {{range .Commands}}
                                {{if not .Runnable}}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}
                {{end}}
                {{if gt .Parent.Commands 1 }}
                        {{range .Parent.Commands}}
                                {{if .Runnable}}
                                        {{if not (eq .Name $cmd.Name) }}
                                        {{end}}
                                        {{rpad .CommandPath .CommandPathPadding}} {{.Short}}
                                {{end}}
                        {{end}}
                {{end}}
        {{end}}
{{end}}

We have a completely unused "{{if not (eq .Name $cmd.Name) }}"

Move the {{end}} after the {{rpad...}}

f81b784738 Make flags declared outside spf13.pflag persistent flags on the parent
Some projects pick up flags from other projects they include.  A great
example would be projects that use glog and thus get all of those flags.
Kubernetes, for example, merges those flags manually into its commands.

This was reported in https://github.com/spf13/cobra/issues/44

What this patch does is merge those flags into the PersistentFlags on
the highest parent.  This allows kubernetes to stop having to merge
things themselves...

6de96b849c Default usage output to stdout
If the command has not set an output explicitly everything will go to
stderr.  This makes a lot of sense, but is a huge PITA for people who
want to be able to grep the help output.  It is very common for users to
want to do

command --help | grep flag

This patch fixes that by default help output (but not error output like
an invalid command) to stdout instead of defaulting to stderr.
