  Fix line numbers in error messages for mismatched tags
  
  Commit 62150ed2 introduced a small regression in the error messages for
  mismatched tags. This typically only affected messages after the first
  mismatch, but with custom SAX handlers all line numbers would be off.
  
  This also fixes line numbers in the SAX push parser which were never
  handled correctly.
