Fix for BUG#1096 which is:

"mysqlbinlog does not comment the original LOAD DATA INFILE if it has a "use xx""


client/mysqlbinlog.cc:
  a comment
sql/log_event.cc:
  in mysqlbinlog we want to have a leading '#' before LOAD DATA INFILE when we
  print a Create_file event.
  This was not done properly when the query had *2* lines: only the "use db" got
  commented.
  To fix this I had to add an argument to Load_log_event::print, it could not be
  handled in Create_file_log_event::print alone.
