[PATCH 5/6] chattr.1: clarify that ext4 doesn't support tail-merging either

[Eric Biggers <ebiggers@kernel.org>]

From: Eric Biggers <ebiggers@google.com>

This old text was never updated to mention ext4 in addition to ext2 and
ext3.  Do so now.  Also don't bother to mention old unmerged patches.

 directory hierarchies for the purposes of the Orlov block allocator.
