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.

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.

Looks like copy'pasta and an unused variable

The default pflag error is to only print the bad flag. This enables an application
to include a usage message or other details about the error.
