Expected or not, it's a serious bug. If it doesn't canonify the
filename, it should return an error. Lying by returning success is
horridly wrong. And I might just suggest that as people are now
accustomed to typing mixed-case filenames, it's a bug that's likely to
occur more frequently than it might at first seem.
