bsdtar(1) line_reader.c interesting code part - partial patch

Hi,

Bug report sais:

http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/144786

bsdtar(1) doesn't support multi line matching or it is broken.

This patch [1] should solve it but not sure about this line in the 
original code:

if (lr->nullSeparator) {
...
}

This is  constant '\n' so this code part was never reached. This is why 
the '\n' separated lines were handled as one long line.

The line_reader.c header comment sais:

  * Read lines from file and do something with each one.  If option_null
  * is set, lines are terminated with zero bytes; otherwise, they're
  * terminated with newlines.

But where is the switch to change between \n and zero bytes? :)
