[Bug-tar] can't deal with junk in front or back

[Dan Jacobson]

Disappointed that junk in front can't be dealt with:

$ tar c /etc/motd /etc/motd|{ echo xxxxxxx; cat;}|tar tv
tar: Removing leading `/' from member names
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Error exit delayed from previous errors

Couldn't it find the next header then like it said?

Disappointed that trailing junk isn't even mentioned

$ tar c /etc/motd /etc/motd|{ cat; echo ccccc;}|tar tv
tar: Removing leading `/' from member names
-rw-r--r-- root/root       362 2003-12-17 23:56:09 etc/motd
-rw-r--r-- root/root       362 2003-12-17 23:56:09 etc/motd

[Maybe also identical archive names could be warned to stderr.]
