How to set unlimited scrollback ?

[772279]

Currently, one of the commands produces 2K lines to stdout but I have observed that the maximum number of lines in an vterm buffer is 1055. How do I set this to unlimited lines (or at least increase this limit) so that I can go back more in my command output.

I was able to set

(setq vterm-max-scrollback 100000)

and was able to increase the scroll back to 100000. I saw the comment here that we can set the upper limit to more than 100000 by setting SB_MAX and re-compiling it.

I'm leaving the issue open because the ideal behaviour here is to have SB_MAX to the maximum allowed value on the machine and make the user configure it via vterm-max-scrollback in their emacs config.
