client/mysqltest.c:
  Fix bugs in 'read_line' function, add better comments and some DBUG printouts
  Add do_delimiter function so the "delimiter" command is parsed better, it should not be allowed to have emtpy delimiter 
  Add checks that disable/enable_pasring is not used when it's already disabled or enabled.
  Don't allow mysqltest to end with parsing disabled
  Add function 'convert_to_format_v1' as the bugs in read_line caused the queries to be read a little funny
  and we want to preserve the result file format(at this time)
mysql-test/r/mysqltest.result:
  Update result file
