  Thanks @xiyangxixian

  single line comment in sql will merge next line into before one.

  trimspace before check single line comment

  SplitStatement check if single comment line is in multi-line sql.

  pure comment line should break quickly, single comment in multi-line
  sql should wait for line delimiter

  multi-line comment will cause line counter error, when
  -report-type=lint

  1. SplitStatement mulitstatement eof bug
  2. empty query by pass
