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

92ea23a837 Fix subcommand locations with NoOptDefValue flags (#391)
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.
