cpio copy-in and multiply-linked files

[Chris Jaeger]

Hi,

        I was wondering whether it was a bug or a feature
that GNU cpio, while in copy-in mode, will create a 
multiply-linked set of files all of size 0 if the last
linked file is not copied in due to the pattern select.
For example, if I have three files a, b, and c, which
are all linked to the same data in a cpio archive, and
I unpack a and b only, but not c, then a and b are created
with size 0, regardless of the size of the data associated
with file c.

        Any input is appreciated.

Thanks,
Chris
