Fix the comment: consistent with others

* add go.mod and go.sum (#833)
* chore(travis): move 'diff' job to separate stage in Travis (#839)

* chore: update viper to v1.3.2 and go-md2man to v1.0.10
* fix: convert CRLF to LF when comparing files
* use kyoh86/richgo to provide colored test outputs
* 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
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.
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.

* Fix tests so they give correct args
Shell already deletes all quotes and unite args under quotes, so we
don't need to test it.
* Simplify stripFlags
* Fix 'unused' and 'gosimple' complaints
* Delete Eq, Gt, appendIfNotPresent and trim functions
* Add "[flags]" in UseLine
* Simplify other functions
* Simplify templates
Minor performance improvement.
Benchmark for command with 4 flags and one child command:
benchmark old ns/op new ns/op delta
BenchmarkCmdUsageFunc-4 335860 319290 -4.93%
benchmark old allocs new allocs delta
BenchmarkCmdUsageFunc-4 562 543 -3.38%
benchmark old bytes new bytes delta
BenchmarkCmdUsageFunc-4 21623 21037 -2.71%
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.

I think It's more obvious now to understand the inheritance of flags.
