The fact that my/diff-refine-all-hunks does not call diff-refine-hunk is
a good indication that your code is at least brittle, since it relies on
some side-effect of diff-hunk-next.
What you're seeing is that diff-hunk-next's use of diff-refine-hunk is
only meant for interactive use, so all it does is schedule
diff-refine-hunk to be run "at the end of the current command".
