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

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.

f20b4e9c32 Refactor TakesArgs to use an interface for arg validation.
Fix some typos in README and comments.
Move arg validation to after flag validation so that the help flag is run first.
Pass the same args to ValidateArgs as the Run methods receive.
Update README.

Check that arguments are in ValidArgs

If a command defined cmd.ValidArgs check that the argument is actually
in ValidArgs and fail if it is not.
