[PATCH] stat: replace file system type "ext2/ext3" by "ext2/ext3/ext4"

[Bernhard Voelker]

I noticed that my ext4 file system was reported as
"ext2/ext3" by "stat -f". Would it harm to add "ext4"?

Have a nice day,
Berny

   nl no longer supports the --page-increment option which was deprecated
   since coreutils-7.5.  Use --line-increment instead.

+  stat -f now reports the file system type 0xEF53 as "ext2/ext3/ext4".
+  Before, it would only print "ext2/ext3".

   Perl is now more of a prerequisite.  It has long been required in order
