[Bug-tar] warning changes return code when using tar -cjf

[rodolfo gouveia]

Hi all,
I discovered that when using tar and compressing with bzip2 like:

 $ tar -cvjf backup.tar.bz2 /backup ; echo $?
 tar: Removing leading `/' from member names
 tar: /backup/alwayschanging.log: file changed as we read it
 1

I get the 1 as the return code when in the documentation [1] says:
 Warning messages are output to the standard error and they do not 
affect the exit code of tar command.
which is correct if I don't use the -j flag for bzip2.
Maybe the documentation should mention this caveat.

cheers,
rodolfo
