* Fix stderr printing functions
Follow-up of #822
* Errors go to stderr as per POSIX
* use PrintErrf() instead of extra call to Sprintf()
* Error messages should always be printed to os.Stderr.
* add test case for Print* redirection
Thanks: @bukowa for the patch.
Replace the current Zsh completion with a Zsh completion solution based
on Go completions. This allows to support custom completions (based
on Go completions), but also to standardize the behavior of completion
across all shells.
Also, add support to Go completions for the bash completion annotations:
BashCompFilenameExt (including Command.MarkFlagFilename() family)
- still supported by zsh
BashCompSubdirsInDir - now supported by zsh
BashCompOneRequiredFlag (including Command.MarkFlagRequired() family)
- now supported by zsh and fish
Finally, remove the suggestin of the = form of flag completion.
The = form is supported, but it will not be suggested to avoid having
duplicated suggestions.

Trivial addition to the first example in `README.md` that defines the
`cmd.Execute()` function that is referenced further down in the `main.go`
example.
Update Cobra generator to make rootCmd private rather than
exporting it. Also update examples in README to use the exported
Execute() command rather than referencing unexported rootCmd.
Fixes#556
