Unstick Terminals in Emacs

I’ve used multi-term for years in emacs as my primary terminal interface. It works great, but occasionally while ssh’ing to another machine and using the emacsclient -t interface (my common approach), the terminal gets stuck to a too-small size. This happens most commonly when my ssh session crashes and I have to start a new one.

It turns out the cause of this is that the terminal is taking its measurements from the other emacs window it’s bound to, and if you unbind it, it’ll be willing to take measurements from a new window.

So all you have to do is

(replace-buffer-in-windows)

… and then navigate back to the terminal buffer to get it to resize appropriately.
