Add test to demonstrate issue

This test demonstrates issue #5206 in my environment. If you have vagrant installed, I can share my configuration with you so that you can easily bring up an environment to see and test this in. Let me know.

It also happens on other commands with arguments, but I opted for `echo` since its easiest to test versus something like `mysql -e "show databases" | fgrep {{ item }}` which ignores the `-e`.
