#10815: Boost 1.55 property_tree INFO parser does not round-trip for \t (tab)
-------------------------+-------------------------------------------------
 Reporter:  brewmanz     |       Type:  Bugs
  <brewmanz@…>           |  Milestone:  To Be Determined
   Status:  new          |    Version:  Boost 1.55.0
Component:  None         |   Keywords:  property_tree INFO round-trip \t
 Severity:  Problem      |  tab
-------------------------+-------------------------------------------------
 Following GTest fails, as embedded tab (\t) has been expanded to a 'real
 tab' by write_info (note that \n, \0, \r are all escaped properly
