  Modified files:
    sbin/restore         restore.c 
  Log:
  In createfiles(), properly handle a number of cases where no further
  volumes are available, instead of getting stuck in a loop calling
  getvol(). Normally restore in 'x' or 'i' modes will ask for a new
  (earlier) volume when the current inode number on the tape is greater
  than the last inode to be restored, since there can be no further
  inodes of interest on that volume. However we don't want to change
  volumes in this case either if the user explicitly said that there
  are no more tapes, or if we are looking at the first volume.
  
  When no more volumes are available but there are still inodes that
  we have not found, we now just fall through to the code that prints
  out a list of any missing files, so the restore completes normally.
  Also simplify the logic a bit by always returning to the start of
  the main for(;;) loop whenever the volume has changed.
  
  This should completely fix the "Changing volumes on pipe input" bug
  that is often observed when restoring dumps of active filesystems.
