5b121bc9fb Template Function Injection
This patch enables developers to add one to many template functions that
can be used by custom Usage and Help templates. Here is an example that
is included in the file cobra_test.go as the test function named
TestAddTemplateFunctions:

    AddTemplateFunc("t", func() bool { return true })
    AddTemplateFuncs(template.FuncMap{
        "f": func() bool { return false },
        "h": func() string { return "Hello," },
        "w": func() string { return "world." }})

    const usage = "Hello, world."

    c := &Command{}
    c.SetUsageTemplate(`{{if t}}{{h}}{{end}}{{if f}}{{h}}{{end}} {{w}}`)

    if us := c.UsageString(); us != usage {
        t.Errorf("c.UsageString() != \"%s\", is \"%s\"", usage, us)
    }

In the above example four functions are added to the template function
map used when the Usage and Help text is generated from the templates
that enable custom logic as well as data injection during template
execution.

This should let users overwrite it with something custom. Like the help
sub-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.

1e6fdf608f Add new BashCompSubdirsInDir annotation
This first `cd` to a specified directory, then
lists the subdirectories therein with `_filedir -d`.

This can be used by e.g. `hugo --theme=[Tab][Tab]`, which would
give a list of subdirectories under the `themes` directory.

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.

0a7a850026 Make error handling more obvious
Again, the code looks a little more like a middle-schooler's code. But
that just makes it easier to understand and maintain.

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.
```

1d99c8ff6d genmarkdown: add optional frontmatter- and linkadjustment-funcs
The automatic Markdown generator works great!

But to use it to render the documentation in Hugo, we need front matter and slightly different links.

This commit adds optional callback funcs to add that.

dff410ab56 make filename extension handling a bash function
We were trying to call a bash function with bash stuff like @ () from a
variable.  Stop that.  Just call a function with an arg from a variable
instead of trying to pass around the bash.

Should fix https://github.com/spf13/cobra/pull/103
