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.

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.
