confusing overwrite dialog when copying folder from case-sensitive to case-insensitive file-systems

Description

If a folder on a regular linux file system contains files "Foo" and "foo", and the user tries copying that folder to a regular USB stick (typically FAT formatted), she gets a dialog asking whether to overwrite "Foo" with "foo" or vice versa.

This is scary and confusing. Perhaps Thunar could, before copying to such case-insensitive file systems, do the equivalent of "tr [upper] [lower]|sort|uniq -d" before recursing into a folder, auto-rename to avoid the conflict, and then let the user know what was done.
