I've been working on a program to address this issue, called reflow. It runs a process ($SHELL by default) and keeps a text buffer of the last 2^16 characters. It's not really a scroll back buffer however - reflow does not (currently) support scroll back. All it does is detect a SIGWINCH and then reprint the entire buffer. The reason it prints the entire buffer is so that your terminal's scroll back will still function as expected. I've though about having it only print out what's needed, but if I do that I'll need to add a scroll back buffer. It's also quite difficult dealing with all the various ANSI escape characters that will change the number of characters I need to print out. It's written mostly in OCaml (with some C to interface with functions not found in OCaml's Unix library). I haven't worked on it in awhile since I've been contributing to OCaml's ExtUnix library, but the program works. Actually, I need to push some more changes to github as I have a better build system setup for it now. Anyway, if you are interested check it out: https://github.com/aplusbi/reflow -Niki
