If the developer is missing any dependencies, for instance `github.com/spf13/cobra/cobra`, `go install` will fail:
```bash
../../spf13/viper/util.go:29:2: cannot find package "gopkg.in/yaml.v2" in any of:
/Users/campoy/src/golang.org/x/go/src/gopkg.in/yaml.v2 (from $GOROOT)
/Users/campoy/src/gopkg.in/yaml.v2 (from $GOPATH)
```
While `go get github.com/spf13/cobra/cobra` will build the tool successfully.
As persistent flags of parents can only be added, we don't need to always
check them every time, so make updateParentsPflags return only added flags.

I think It's more obvious now to understand the inheritance of flags.

command_test.go:198: expected setting output to nil to revert back to stdout, got <nil>
Docker (https://github.com/docker/docker) now
also uses Cobra for the CLI. A majority of the
commands have been migrated (still some left),
but adding it already :)

If one ran a command like
./root --boolFlag subcmd1 subcmd2
Thing worked fine. The code recognized that --boolFlag followed by a
space meant the next word was not the argument to --boolFlag. But other
flag types with a NoOptDefValue (like a Count flag) would not ignore the
"argument". On a command like:
./root --countflag subcmd1 subcmd2
The processor, when looking for a subcommand, would first throw out the
`--countflag subcmd1` and then look for subcmd2 under root.
The fix is to ignore the next word after any NoOptDefVal flag, not just
boolean flags.
* bash_completions: cleanup for go vet
The gnarly block of string in the Fprint tripped up go vet and was not
easy to read.
