So, it's not automatic, needs user interaction, and for that reason,
may not have worked for me. (I have other weird things in my prompt,
like 256-color sequences that Emacs didn't recognize, perhaps this
made the regexp matching fail. Nevermind.)

iTerm2 has a "shell integration" where the prompt contains explicit
markers so that no heuristics or user configuration is needed from the
terminal. We're trying to somewhat standardize it at and
get more terminals support it. Not sure where this attempt will take
us, we'll see.

25.2 here, it might have obviously changed for a newer version, glad to hear it.

My distro will upgrade in about 2 months. Since I'm not an Emacs user
myself, I hope you don't mind if I don't make extra rounds in
upgrading now to verify this.
