Tim Peoples eb58983359 Add `CalledAs` method to cobra.Command (w/ tests) (#567)
* Add `CalledAs` method to Command (w/ tests)

The `CalledAs` method returns the name of the command or alias that
invoked the command -- as long as the command was actually invoked.
Otherwise, it returns the empty string.

The opens up possibilies for commands to behave differently based on
which alias invoked the command (in the same vein as Linux programs
which adjust their behavior based on the value of argv[0]).

* Fixed formatting

Nick Miyake ccaecb155a Ensure that '--version' flag works properly for root command (#595)
Make it so that, in the case that the root command is not runnable
but has subcommands, specifying a '--version' flag will still
run the "version" behavior.

in ValidArgs and fail if it is not.

Albert Nigmatzianov 3d89ed4908 Add only missing persistent flags of parents in mergePersistentFlags
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.
