I've just read notes about "Comint Patch":

  ╭────
  │ If you enter a multi-line SQL statement in an SQLi buffer, you can
  │ retrieve it as a multi-line command from the MinibufferHistory. Not so
  │ when you exit Emacs and restart it at a later date: As you exit SQLi
  │ mode the command history is written to a file; when you enter SQLi mode
  │ again the history is loaded one command per line. If you entered
  │ multi-line commands, each line of those commands will end up as one
  │ command in the input history of your new session.
  │ 
  │ This patch will be in Emacs 21.

Aren't we talking of this bug?  If yes, why isn't it yet in Emacs, then?

Best regards,
