withFileNames :: Maybe [OrigFileNameOf] -> [FileName] -> FilePathMonad a -> FilePathMonadState

withFileNames takes a maybe list of existing rename-pairs, a list of filenames and an action, and returns the resulting triple of affected files, updated filename list and new rename details. If the rename-pairs are not present, a new list is generated from the filesnames.
