Apologies Steffen, I grabbed your CamelCase test and did a search/replace,
wasn't sure what to call it though... But I am on lunch and wanted to be
useful. Rip it apart all you want.

Fails on hfs* on OSX, works on ufs. I will bother with zfs when it can be used
again.

On UFS:
$ /bin/sh ./t0060-normalization.sh
*   ok 1: setup
*   ok 2: rename (silent normalization)
*   ok 3: merge (silent normalization)
* passed all 3 test(s)

On HFS:
$ /bin/sh t0060-normalization.sh
*   ok 1: setup
* FAIL 2: rename (silent normalization)

     git mv ä ä &&
     git commit -m "rename"

* FAIL 3: merge (silent normalization)

     git reset --hard initial &&
     git merge topic

* failed 2 among 3 test(s)

The test case, it uses perl, assuming only 5.6.1+ will work with this:
