Partially rollback previous change adding Turkish path normalization.

We've determined that NTFS does not do locale-dependent case mapping (and neither do any other file systems we know of), so providing this option is unnecessary and misleading.

I'm leaving the removal of a TODO I had to consider allowing Turkish-correct case folding and also adding in some notes about the whole situation for posterity.
