Hard test cases for hello-world

[bkeepers]

I found the last two test cases for the hello world example to be rather difficult.

I don't consider myself proficient in bash by any means, but I have written my share of shell scripts. Figuring out how to detect if there are zero arguments vs a blank argument in bash seems like an intermediate challenge.

Could they be moved to a different exercise later on?

Yeah, it seems like Hello World should be really, really straight-forward. Let's start by removing the test cases from hello world, and we can leave this open to make sure to add them to something else later.

This can be closed, right?

I think this is left open in hopes to add a Bash exercise where argument validation and arity are being covered.

Is there an exercise that does this in the track yet?

Rikki issue created for intro comment. This should be a easy testing, easy solve, proof of "You got here and here is where you should be!" kind of exercise, with a comment that communicates "Congratulations on the submission, welcome to the Bash track, normally we would review others submissions, as well as exercism fetch bash to get the next exercise..."

This was resolved in #52 where we add the new 'two-fer' exercise to replace 'hello-world', and simplify hello-world.
