By default, jump to the new source file; jump to the old source file

- `diff-jump-to-old-file' is non-nil and you don't supply a prefix
argument (when called from Lisp, optional argument OTHER-FILE is nil)
- `diff-jump-to-old-file' is nil and you supply a prefix argument
(when called from Lisp, optional argument OTHER-FILE is non-nil)
By default, jump to the new source file.
With a prefix argument (when called from Lisp, with optional argument
OTHER-FILE non-nil), jump to the old source file.
If `diff-jump-to-old-file' is non-nil then the meaning of the prefix
argument (or, when called from Lisp, the meaning of optional argument
OTHER-FILE) is reversed: a prefix argument (respectively, OTHER-FILE
non-nil) means to jump to the new source file, and the lack of one
(respectively, OTHER-FILE nil) means to jump to the old source file.
In addition, if you supply a prefix argument bigger than 8 (for example
with \\[universal-argument] \\[universal-argument]), \
the value of `diff-jump-to-old-file' is toggled for the
