Sorry, I can't help you with that. But I can tell you that (buffer-size)
should almost certainly be (point-max). And you might want to add a check
for (eq major-mode 'lisp-mode), or make after-change-functions a local hook
variable in Lisp mode buffers (by putting the add-hook in a lisp-mode-hook
function, and specifying the optional LOCAL arg).
You might also have better luck if you call indent-region with a region
that starts at the beginning of the line:
(save-excursion (goto-char start) (line-beginning-position))
