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.

d89c499964 Allow commands to explicitly state if they do, or do not take arbitrary arguments
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.

3d89ed4908 Add only missing persistent flags of parents in mergePersistentFlags

check them every time, so make updateParentsPflags return only added flags.

7aeaa2cce6 Avoid storing pointer to nil (#411)
* Fix shellcheck

Before this change:

	In - line 204:
	    declare -F $next_command >/dev/null && $next_command
	               ^-- SC2086: Double quote to prevent globbing and word splitting.

	--- FAIL: TestBashCompletions (0.34s)
		bash_completions_test.go:138: shellcheck failed: exit status 1

* Avoid storing pointer to nil

Before this change, the new test fails with:

	--- FAIL: TestSetOutput (0.00s)
		command_test.go:198: expected setting output to nil to revert back to stdout, got <nil>

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.

67feb8173c Add support for setting a function to handle flag parsing errors.
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.
