As an aside, probably would have been easier to include this in the
original message, rather than add a link.
bc.el looks like this:
(let ((p (start-process "bc" (current-buffer) "bc")))
(process-send-string p "2^10\n")
(goto-char (point-max)))
The strange thing here is that it's not specifically an undo problem.
Point doesn't move after eval-defun. You don't need to do undo to see
the difference.
This on the other hand:
(let ((p (start-process "bc" (current-buffer) "bc")))
(process-send-string p "2^10\n")
(sit-for 1)
(goto-char (point-max)))
Works fine.
I will investigate.
Phil
