The only problem I have with the rename is with __filename_parentat() there is a nice uniformity: filename_* functions consume the passed name, and __filename_* do not. So maybe it's something nice to have. Maybe not. Anyway, as I've mentioned, I'll send the patch and it can be either picked up or ignored. -- Dmitry
