5.22 How can I make Emacs automatically scroll horizontally?

In Emacs 21 and later, this is on by default: if the variable truncate-lines is non-nil in the current buffer, Emacs automatically scrolls the display horizontally when point moves off the left or right edge of the window.

Note that this is overridden by the variable truncate-partial-width-windows if that variable is non-nil and the current buffer is not full-frame width.

In Emacs 20, use hscroll-mode.
