Let /tmp/scroll-conservatively-1.el have this content:
(setq scroll-conservatively 1)
(add-hook 'term-setup-hook (lambda () (goto-char (point-max))))
And /tmp/foo.cpp as attached.
Also set the keyboard repitition rate somewhat high.
Start Emacs by: emacs -Q /tmp/foo.cpp --load /tmp/scroll-conservatively-1.el
Hold arrow up key, recentering occurs while scrolling up.
Note: Script goes to EOB because I only witness this for scroll ups, not scroll downs.
I witness this regularly when navigating C++ source code.
