example pulling github.com/flynn/go-shlex

[orgrim]

Hello,

By using your module, I've found that github.com/flynn/go-shlex gets pulled as dependency. It is because it is used in the example_test.go file, but not required.

Would putting it in a examples/ subdirectory and updating go.mod avoid that?

Thanks and regards

I also think module dependency for comparative example is not desirable.

And because github.com/flynn/go-shlex is not updated for a long time, I remove this pkg.
