anagram: Should we case about case sensitivity and/or duplicates?

[rbasso]

The way the anagram exercise is implemented, we demand that the the word comparison is case-insensitive, but we also demand keeping the original word's casing.

Should we lowercase everything before comparing? Is keeping the original word's case part of the exercise?

I guess that is another case of "requirements only implicit in the test cases but not in the README", just like in #547 . It was made this way in exercism/problem-specifications#201

Let's hear a reason to change it

(Otherwise I do not care to change)

Let's leave it the way it is!

If someone complains we can change it later.
