FIFOs break tar, others

[Karl Lehenbauer]

Tar will hang when it tries to open FIFOs.  Cpio and even 'cp' will
too, but the find command that is typically piped into 'cpio -o' can 
do a '-type f' so cpio'll never see the FIFO and it could be argued
that 'cp' should not have to look at file types.  Well and good.

tar, unfortunately, cannot be told to ignore or to properly "copy" FIFOs.
