[Bug-tar] tar: Record size = 8 blocks

[Mads Kiilerich]

Hi,

It seems like GNU tar 1.21 emits warnings when "tar -tf -" get 
unexpected chunk sizes on stdin.

That causes test failure in the Mercurial test suite.

A test case (also filed at 
https://bugzilla.redhat.com/show_bug.cgi?id=487760 ):

$ cat slowcat.py 
import sys
for c in file(sys.argv[1]).read(): sys.stdout.write(c)
$ python slowcat.py test2.tar | tar tf - > /dev/null
tar: Record size = 8 blocks
$


IMHO that is a regression from 1.20. Can you recommend a patch to 
restore the silence?
