note 14641 added to function.fileinode.php

Partly correct: The Unix-inode contains modification-time, file-size, type and other info about a file, but not its directory. A directory under Unix is like any other file, only that instead of text or other data it contains a list of names and inodes. A file under Unix can therefore be accessed by multiple names from different directories, but has only one inode. A counter in the inode keeps track of how many links point to this inode; only when the last link to the inode is removed (unlinked), the file is deleted too. Another correction: FileInode() existed in PHP/FI 2 as well, but with a slightly different behaviour. http://www.php.net/manual/en/function.fileinode.php
