Hello,
When typing multi-line commands (on purpose, or because of a missing
component), they end up as standalone lines in the shell command history:
> ls \
> *.html
Recalling the previous command will just show "*.html", not "ls \\n*.html".
Is there a solution to this?
Best regards,
Sebastien Vauban

Right, currently shell-mode has no idea that these were two lines of the
same command. The semantics of a terminating backslash completely
eludes it.

A patch for shell.el would probably do it, assuming it's the right patch ;-)

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,
Seb

I can confirm that this behaviour is still present in Emacs 28.

Presumably nobody submitted it -- and that URL doesn't exist any more.
Does anybody have the patch in question?
