>Description:

If i create an empty 5G sparse file,

-rw-r--r--  1 nox  wheel  5368709120 Sep 28 23:05 sparse

and archive it with gtar (result uuencoded below), then gtar tfvz
lists it correctly as:
-rw-r--r-- nox/wheel 5368709120 Sep 28 23:05 2005 sparse

but bsdtar lists it as:
?rw-r--r--  0 nox    wheel 1073741824 Sep 28  23:05 sparse

(btw what does the ? stand for?), and extracts it to a 1 byte file.
And even if its not empty (e.g. install 4.11 into it using it as a
raw qemu disk image), bsdtar lists it with the wrong size.
