New Revision: 198702
URL: http://svn.freebsd.org/changeset/base/198702

Log:
  When reading input from a file or device (via -f option) set the
  input to be in non-buffering mode so that input lines are logged
  as they occur rather than being saved up until a buffer's worth of
  input has been logged.
