I checked, and at least recent versions of e2fsck complain/fix immutable
flags on device files, fifos, and sockets.  The below check disallows
immutable or append-only flags on symlinks (on the grounds that it is not
possible to set these legally).

Now what I need to do is also add an e2fsck test case for this...
