[BZ#644759] Case sensitive comparison on case preserving, case insensitive file system duplicates entries
Originally submitted by Kai Willadsen in bugzilla (#644759):
In directory comparisons, we construct a tree which represents a union of paths across the multiple directories being scanned, and then ask whether each path exists. Case preserving, case insensitive file systems will (or at least, may) answer 'yes' to the existence of both README and Readme, leading to duplicated entries where both cases are used in different directories.
